A flow meter in the return line to a hydraulic reservoir reads 18 gal/min. How large would the suction line have to be to limit the velocity to 3 ft/sec?

Assuming the flow into the tank is maintaining the water surface elevation at a constant location, what is the flowrate (L/s) coming out of point 2? (1) D 0.20 m h 0.20 m (2) (3) d 0.01 m (b)

Problem 1: A constant head tank delivers water through a uniform pipeline to a tank, at a lower level from which the water discharges over a rectangular weir. If pipeline length 20 m, diameter 100 mm, roughness size 0.2 mm, length of weir crest 0.25 m, calculate the steady discharge and head over the weir crest. (take Cd = 0.6) %3D H.
