A single-stage centrifugal pump having a suction pipe 254 mm in diameter anda discharge pipe diameter of 5 inches is being tested and found out to discharge 48 lps ofwater. A pressure gage connected to the inlet pipe reads 118 mm Hg vacuum and adischarge gage reads 150 kPa at a distance 100 cm above the point where the inletpressure was measured. If the kW rating of the driving motor is 12 kW, calculate a) the pump efficiency. b) if this pump runs at 1800 rpm, what will be the new discharge rate,head, and power developed if the pump speed was increased to 3600 rpm? Assumeconstant efficiency. c) Determine the pump type.

1Two water pumps are arranged in series. The performance data for both pumps follow the parabolic curve fit Havailable =H0 =aV ^2. For pump 1, H0 =5.30 m and coefficient a =0.0438 m/Lpm^2; for pump 2, H0 =8.70 m and coefficient a =0.0347 m/Lpm^2. In either case, the units ofnet pump head H are m, and the units of capacity V are Lpm.Calculate the combined shutoff head. Complete Answer, thank you
