Calculation Sheet

- Pump Hydraulics

이 Calculation Sheet는 Process Engineer가 빈번하게 수행하는 Pump Hydraulics Calculation을 정확하고 일관성 있게 계산 할 수 있도록 하기 위하여 준비되었다.

이 Calculation Sheet는 하나의 Pump에 대하여 가간단한 scheme을 sketch하고 fluid의 properties를 입력한 후 그에 따라 정해진 line의 pressure drop을 구하고 pump hydraulic을 수행하여 그 결과를 pressure profile에 정리되도록 구성하였다.

Fluid type은 Liquid flow, Vapor flow, Mixed flow로 나누어지므로 line differential pressure calculation sheet를 3가지로 나누어 두어서 fluid 종류에 따라 달리 구해지는 결과를 정리할수 있도록 하였다. 그 외에 line의 fitting 구성에 따라 변경되는 equivalent length를 계산하기 위한

'EQ_L Calcaulation' sheet를 가추 하였다. 또한, line pressure drop을 계산하기 위한 Pipe line의 ID를 정리한 sheet가 포함되었으며, sketch의

편의를 위해 가각 equipment 및 element의 그림을 Drawing sheet에 가추 하였다.

Control Valve의 pressure drop calculation method는 no control valve, Conventional, LDM 중 선택하여 계산 되도록 하였으며 Manual input을

이용한 방법도 포함하여 project specification 을 따르거나 혹은 상황에 따라 달리 적용해야 할 경우에 사용할 수 있도록 하였다.

Report에는 Coversheet, Pump Calculation, Sketch, Pressure Profile이 포함되고, Equivalent Length와 Line Pressure drop calculation은 계산시 활용하며, Guideline과 Equivalent Length, Pipe ID는 계산시 참고자료로 사용한다.

이 Calculation Sheet에 Green Blank는 Calculation을 위하여 사용자 직접 넣어주어야 하는 가값이며 Yellow Blank는 주어진 정보를 기준으로가

자동으로 계산되는 가값이다. 가각 Sheet에 대한 소개는 다음 Section에 기술하였다.

양식은 Hydrosys output excel file 을 참고하였으며, Green Blank 를 직접 넣어주면 Yellow Blank에서 계산되어 자동으로 fill-up 된다.

Pump suction은 Rated flow 에서의 입력가값 을 기준으로 Normal 과 Minimum flow에서의 가값들을 유도하였으며, Pump discharge 는 Normal flow

가값

에서의 을 기준으로 Rated 와 Minimum flow에서의 가값들이 자동으로 계산된다.

Control Valve pressure drop은 Control valve calculation method, control valve type, reflux 유무에 따라 달리 계산되게 하였다. 이를 선정해 주면 가각 방법에 따라 달리 계산되어, Control valve DP란에 자동으로 입력된다.

해당 Pump Circuit을 Hydraulic calculation의 편의를 위해 개략적으로 그린다. User의 편리함과 drawing의 통일성을 위해 print 되지 않는 영역에

symbols을 그려놓았고, 이를 복사에서 사용하면 된다. Job no. 와 Project name, Client 는 Coversheet에서 불러오며 그밖의 Green Blank는

User가 직접 채워 넣는다. 그러면, Pump Calculation, Pressure Profile, Equivalent Length Calculation sheet 도 자동으로 변경된다.

가

사용자 더 많은 data를 sketch를 통해 가간략히 확인하고 싶을 경우, 직접 input하거나 다른 sheet에서 계산된 결과가값을 불러오면 된다.

Case별로 sketch가 다르고 equipment, instrument 의 개수와 종류 다양하기 때문에, Pressure Profile 가 의 공란은 user가 직접 입력해야 한다.

Section 혹은 equipment, instrument 별로 pressure drop을 입력 하거나 link시키고, 가각 point에서 static head를 계산하여 inlet pressure를 계산한다. 양식은 HydroSys output excel file을 참고하였다.

External Fire Case에 대한 Relieving Load를 계산하는 경우 고려되어야 하는 Environment Factor, Latent Heat을 Table,

Calculation Sheet

- Pump Hydraulics

User가 Nominal Diameter 와 Enlarger, Reducer 의 size 를 결정하고, 가각 종 fitting 의 개수를 green blank 에 입력하면 'EQ_L Calculation' sheet는

yellow blank에 'Euivalent Length' sheet에서 data를 읽어온후 합산을 한다. Overdesign의 사용 유무와 사용시 %를 입력하면 최종적으로 계산된 equivalent length가 표시된다.

가각 section 및 segment 별로 나눠서 계산한 뒤 line pressure drop의 100m 당 pressure drop과 함께 'Pressrue Profile'에 정리한다. 이를 곱하여, pressure drop을 계산하면, 'Pressure Profile'이 완성된다.

Line Differential Pressure Calculation for Liquid Flow을 위한 sheet이다. Pump circuit의 liquid line의 pressure drop을 darcy equiation을 이용하여

계산한다. Flow rate, density, viscosity, roughness 와 nominal size 와 schedule 을 통해 계산된 pipe ID 로 100m 당 pressure drop 과 velocity를

구하고, 'Guideline'을 참고하여 pressure drop과 velocity limit을 입력하여 비교한다.

여기서 구해진 100m당 pressure drop은 앞에서 계산된 equivalent length와 함께 line의 pressure loss를 구하는데 사용된다.

이 sheet 는 "GDP-6BDT-404 Line Sizing Calculation sheet" 를 참고하였다.

유체의 Control valve 후단 압력가강하에 따른 상변화나, Heat exchanger 에 의한 온도변화에 따른 상변화등, Pump circuit에서 발생할 수 있는

two phase fluid의 line pressure drop 계산을 위해 첨부하였다.

Fluid 의 Properties와 condition을 입력하면, Homogeneous model과 Duckler method를 이용하여 pressure drop 및 velocity, vapor volume fraction을 계산하고, Baker Chart와 G-W Chart를 통해 flow regime, Average / Inplace density를 계산한다.

Line Differential Pressure Calculation for Vapor Flow을 위한 sheet이다. Pump circuit에 포함될 수 있는 vapor line을 isothermal method를 통해 계산한다. Flow rate, molecular weight, viscosity, Z, k(Cp/Cv), pressure, know Pressure(upstream or downstream), temperature를 입력하면

100m당 pressure drop 과 velocity가 계산된다.

Line Differential Pressure Calculation에서 계산되는 pressure drop 과 velocity 의 limit 를 제시해 주는 guideline이다.

Process, 용도, line의 위치에 따라 limit가 다르기 때문에 적절히 적용해야 한다.

Equivalent Legth calculation에 쓰이는 database 로 LDM 의 chart 를 옮겨 놓았다.
