Tutorials

Bentley FlowMaster is an easy-to-use, Windows-based program that aids civil engi-neers with the design and analysis of pipes, ditches, open channels, weirs, and more. Bentley FlowMaster computes flows, water velocities, depths and pressures based on several well-known formulas: Darcy-Weisbach, Manning’s, Kutter’s, and Hazen-Will-iams. It also utilizes the HEC-22 methodology to perform pavement drainage and inlet flow calculations.

Bentley FlowMaster lets you solve for a variable you select, computing the solution from the parameters you provide. The program will also calculate rating tables, and will plot curves and cross sections. These graphs and reports can then be viewed on the screen, copied to the Windows clipboard, saved to a file, or printed on any stan-dard printer.

These tutorials provide step-by-step instructions for creating a project, entering data in a worksheet, and generating reports.

2.1

Overview

The purpose of this section is to provide step-by-step tutorials to get you familiar with some of the features and capabilities of Bentley FlowMaster. The tutorials serve as a means to get you started exploring and using the software.

Note: You should follow these tutorials in sequence.

If you need help within the program, press F1 to access the context-sensitive online help.

2.2

Tutorial 1—Creating a New Project

Data is entered and calculated in a worksheet. There are different worksheets for various structure types, because of the differing input and output data that is required for each.

Worksheets are contained within an Bentley FlowMaster project. A project holds global information such as Project Engineer, Project Date, Project Location (the loca-tion where the project files are stored on your computer), and any Notes that go along with the project.

The project is also associated with a unit system (FlexUnits). The unit system defines the units and display precision used in the project. Upon project creation, the default unit system is used, but this can be modified and saved for use on future projects. 1. Start Bentley FlowMaster by double-clicking the shortcut on your desktop or by

clicking the Bentley FlowMaster command from the Start menu.

2. When Bentley FlowMaster opens, the welcome dialog box appears. Click the

Create New Project button.

4. Click File > Save As. The Save As dialog box opens.

5. Choose the directory to which the file will be saved and type MyTutorial1 as the name for the project file.

Note: We recommend you name the tutorial files you are using

differently than any other files in your program directory, so you don’t overwrite pre-existing files.

6. Now, enter some global project information. Click File > Properties. 7. In the Project Properties dialog box, note the types of information.

The Project Date field should already contain today’s date (this information is retrieved from the Windows system calendar and clock—click the down-arrow button to select a different date by using a calendar). Project File Name contains the path to the directory where the project is saved.

8. Enter the following information in the Project Properties dialog box: – Enter your name in the Project Engineer field.

– Enter Tutorial Project in the Project Notes field.

– If you want your company name to appear on the bottom of all reports associ-ated with the project, enter the company name in the Project Company field. – If you want your company’s logo to appear on the bottom of all reports associ-ated with the project, click in the Company Logo field, then click the Ellipses button and select your company’s logo image file.

Bentley FlowMaster

Environment

The components that make up the Bentley FlowMaster interface are as follows: • “Main Window”

• “Project Explorer”

• “Engineering Library Explorer”

• “Menus”

• “Toolbars”

Any changes you make to the placement and display of the dockable windows and toolbars will be saved, and will persist every time Bentley FlowMaster is started

3.1

Welcome Dialog Box

The Welcome dialog box appears upon startup of the application. The following controls are available:

Create New Project: This button lets you create a new Bentley

FlowMaster project. When you click Create New

Project, a new untitled project is created. The first

time the project is saved, you can specify a name for the project.

Create Worksheet: This button opens the Create New Worksheet dialog box, letting you quickly create a worksheet that is not associated with a particular project.

Open Existing Project: This button lets you open a previously created project.

Show This Dialog at Start: This check box lets you display the Welcome dialog box when ever your start Bentley FlowMaster. Show

This Dialog at Start is selected by default.

Deselecting this check box causes Bentley

FlowMaster to start up at the main window without opening the Welcome dialog box.

3.2

Main Window

The Bentley FlowMaster main window is the workspace in which various project worksheets are displayed. The main window itself does not contain any controls. You can manually position the project worksheets anywhere in the workspace, or use the Window menu controls to automatically position them in a number of ways.

3.3

Project Explorer

The Project Explorer window displays project components in a hierarchical tree view. Data is entered and calculated in a worksheet. There are different worksheets for various structure types, because of the differing input and output data that is required for each.

Worksheets are contained within an Bentley FlowMaster project. A project holds global information such as Project Engineer, Project Date, Project Location (the loca-tion where the project files are stored on your computer), and any Notes that go along with the project.

You can also create folders within a project. These folders can be used to organize your worksheets within the project. The folders are contained solely within the project—new Windows directories will not be created when you create folders in the Project Explorer.

The project is also associated with a unit system (FlexUnits). The unit system defines the measurement and display precision used in the project. Upon project creation, the default unit system is used, but you can modify unit system and save it for use on future projects.

Each worksheet in the project is represented by an icon that indicates the worksheet element type and an automatically generated label.

Various commands are made accessible in the Project Explorer through the use of shortcut menus.

Right-clicking a Project icon in the tree view will open a shortcut menu containing the following commands:

• Add—Hovering the mouse over this command opens a submenu containing the

following commands:

– New Worksheet—This command opens the Create New Worksheet dialog

box, letting you create a new worksheet.

– New Folder—This command creates a new folder under the current project,

letting you organize your project elements.

• Properties—This command opens the Project Properties dialog box, letting you

view and modify basic project information such as date, engineer, location, and notes.

• Save—This command saves the current project.

• Save As—This command saves all currently open projects.

• Close Project—Closes the currently open project.

Right-clicking a worksheet within a project in the Project Explorer will open a shortcut menu containing the following commands:

• Rename—This command lets you rename the currently highlighted worksheet.

• Delete—This command deletes the currently highlighted worksheet from the

library.

• Duplicate—This command creates a copy of the currently highlighted worksheet

in the same project.

• Print—This command prints a report of the currently highlighted worksheet.

• Print Selected Worksheets—This command lets you print more than one

work-sheet at a time and is only available when multiple worksheeets are selected in the Project Explorer. To use this command, first select the first worksheet to print, then Ctrl+click or Shift+click the additional worksheets you want to print. Right-click and select Print Selected Worksheets.

3.3.1

Project Files

Bentley FlowMaster projects comprise the following files:

Note: When transferring an Bentley FlowMaster project, make sure that these files are present, or you will not be able to open it.

Projectname.fm8: This file holds all of the project settings.

Projectname.fm8.mdb: This is a database file that holds all of the input and output data for the project. When emailing or otherwise transferring .mdb files, it is a good idea to compress them using WinZip or another compression utility—the file size will generally be reduced drastically.

Other files that you may encounter in your saved file directories include:

Projectname.fm8.01.bak: This file is a backup file for the FlowMaster project settings file.

Projectname.fm8.mdb.01.bak: This file is a backup file for the FlowMaster data database file.

Projectname.fm8.mdb.ldb: This file is a database lock file. It will be

automatically generated when a project database is currently open, and it prevents changes from being made directly to the database. This prevents data loss and corruption.

3.4

Engineering Library Explorer

The Engineering Library Explorer contains all of the project’s material libraries. Indi-vidual material libraries are compilations of all available materials, and their

attributes. Click View > Engineering Library to see the library.

You cannot modify the default material library that is installed with Bentley Flow-Master. However, you can create a new library that contains any materials that you define.

• “Gutter Section Dialog Box”

• “Irregular Section Dialog Box”

• “Parabolic Channel Dialog Box”

3.8.1

Rectangular Channel Dialog Boxes

The following controls make up the Rectangular Channel worksheet dialog box: • Solve For—This drop-down list lets you select the variable that you are solving

for. The variable that is chosen will appear yellow (read-only) in the list of avail-able input fields.

• Friction Method—This drop-down list lets you select the friction method that

will be used to calculate the worksheet. The Darcy-Weisbach method requires an additional input variable (Kinematic Viscosity) and generates additional output (Friction Factor and Reynolds Number).

• Messages—A Messages tab is included in each worksheet. The top section of this

tab displays informational calculation messages, while the bottom section lets you enter any explanatory notes that you wish to be associated with the worksheet. This dialog box comprises the following tabs:

• “Uniform Flow Tab—Rectangular Channel”

• “Gradually Varied Flow Tab—Rectangular Channel”

Uniform Flow Tab—Rectangular Channel

The Uniform Flow tab comprises an input section on the left and an output, or results, section on the right.

Input:

• Roughness Coefficient—A value used to represent the resistance of a

• Channel Slope—Longitudinal slope in the channel. Also, the vertical drop

divided by the channel length.

• Normal Depth—Distance from water surface to low point of channel bottom.

• Bottom Width—Width of the bottom of the channel cross section.

• Discharge—Volumetric rate of flow, given in units of length (cubed) over time.

• Kinematic Viscosity (This input is only available when one of the

Darcy-Weis-bach Friction methods is used)—Viscosity divided by the mass density given in units of length (squared) over time, hence the term kinematic. Viscosity is a prop-erty measuring the fluid resistance to shear. For example, molasses and tar have relatively high viscosity and water and air relatively low viscosity.

Output:

• Flow Area—Cross-sectional area of flow.

• Wetted Perimeter—Perimeter of flow that travels against a solid boundary. For a

partially full pipe, the wetted perimeter includes all of the flow perimeter except for the top segment, which has a free surface.

• Top Width—Length of the free top surface on the flowing cross section. For a

cross section flowing full, this value is zero.

• Critical Depth—Depth of water in the channel for which the specific energy is at

its minimum. Specific Energy is the sum of the elevation head and velocity head (energy due to the velocity of a liquid) as related to the section of a channel bed. • Critical Slope—Channel slope for which the uniform flow (equilibrium flow for

which the slope of total energy equals the channel slope) is critical.

• Velocity—Linear measure of flow rate given in units of length over time. For

weirs and orifices, the velocity field is for the velocity of the water through the hydraulic structure.

• Velocity Head—Energy due to the velocity of a liquid.

• Specific Energy—Sum of the elevation head and velocity head (energy due to the

velocity of a liquid) as related to the section of a channel bed.

• Froude Number—Dimensionless parameter used to characterize open channel

flow. For critical flow, this value is 1. • Flow Type—The flow is defined as:

– Supercritical if F > 1 – Subcritical if F < 1 – Critical if F = 1
