In Problem 6.31, find the rate of discharge if the frictional head loss in the pipe is 3.2 v²/g where v is the flow velocity in the pipe.

Problem 6.31

Referring to the figure, assume the flow to be frictionless in the siphon. Find the rate of discharge in cubic feet per second, and the pressure head at B if the pipe has a uniform diameter of 1 in. How long will it take for the water level to decrease by 3 ft? The tank diameter is 10 ft.
