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?
With the same flow in all sections of the line, the gradient becomes _____ as the
pipe becomes ____ because of the _____.
The pipe is 2' in diameter, and your flow order is 3.0 CFS. What's the velocity?
, A flume is 2 ft wide and 2 ft deep. It is flowing full of water and the quantity
is measured at 12 CFS.

Velocity (V)

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).
velocity
feet / second (ft/s)
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.
As water flows through a pipeline, there is friction between the water and the
walls of the pipe. It is the resistance to flow of water in a pipe
