Problems
71.A sample of 200 ml wastewater is given in a container (Weight of container = 22.00 g) and was inserted in oven, after water evaporated the weight of sample was given as = 24.502 g
then the sample was inserted in a burning oven and the weight changed to = 22.606 g, the Volatile solids content for this sample is equal to:
=24.502-22.606=1.896 g
Volatile solids content= 1.896 g/200 ml =0.0095 g/ml
72.A car going on a speed of 60 mile/Hr on a curve highway. After passing midpoint the driver saw an accident in front of him. The distance that will be passed from the moment the driver saw the accident until he hit the brakes equal to:
- The perception and reaction time for calculating the sight distance=2.5 seconds -60 mile/hr *5280 ft/3600 seconds=88 ft/sec
- The distance that will be passed from the moment the driver saw the accident until he hit
the brakes = 88 ft/sec *2.5 sec = 220 ft
