Question

A 10 ft diameter tank with a quick opening value to a sump has a 10 ft depth of liquid. How long does it take to drain the tank if the valve is assumed to be equivalent to a 4 in Diameter orifice? The liquid density is 60 lb/ft³

700 gpm of water are being discharged by a centrifugal pump 5 ft above the pump inlet. The inlet pressure is 4 inHg above atmospheric and the discharge pressure is 29 psia. If the pump has an 8 in inlet diameter and 4 in discharge diameter.Calculate (a) the pump efficiency (b) the new flowrate and brake horse power if the pump speed is increased from 1600 to 3200 rp,. Assume the pump input is 8 Hp
