WATER DISTRIBUTION - CLASS 5 QUESTIONS WITH
DETAILED VERIFIED AND 100% ACCURATE ANSWERS
A 16" pipeline is flowing 2,500 gpm. What is the velocity in fps?
Correct Answers Q = 2,500 gpm
2,500/449 = 5.57 cfs = Q
16/12 = 1.33' = D
1.33 x 1.33 x 0.785 = 1.39 sf = A
1.39 x V = 5.57
V = 4.01 f/s
Hydraulics Correct Answers :The study of fluids in motion or under
pressure.
Pressure Correct Answers The force on a unit area of water. Water flows
in a water system when it is under a force that makes it move. Typically
measured in psi or feet of head.
Static Pressure Correct Answers It exists although the water does not
flow. It is at "rest".
Dynamic Pressure Correct Answers Moving Energy.
, Hydrostatic Pressure Correct Answers Static potential energy converted
into moving energy. Example: If water in a column is permitted to
empty from the bottom of the column, the water will begin to flow under
the __________________ applied by the height of the column.
What is the psi a the bottom of a tank with 80 feet of head.? Correct
Answers 80 x 0.433 = 34.6 PSI
The water in a tank is 37 feet high when full. You are in a valve vault
making an adjustment, and you read 11 psi on a gauge that is mounted 9
feet below the floor elevation of the tank. How many feet are in the
tank? Correct Answers 11 PSI x 2.31 = 25.41
25.41 - 9 = 16.41 feet
Velocity (V) Correct Answers The speed at which water moves. It is
usually measured in feet per second (FT/S) in US and meters per second
in metric (the rest of the world).
The quantity (Q) of water that flows through a pipe depends on? Correct
Answers the velocity (V) and the cross-sectional area (A) of the pipe.
Q = ____ and is always represented in ____. Correct Answers flow
cfs
A = ____ and is always represented in ____. Correct Answers area
