A pump with a 150-mm diameter impeller is operating at 1750 rpm and delivering 3.2 L/s with a total dynamic head of 16 meters. The pump's BHP is 3.4 kW (0.45 hp) under these conditions. Assume constant efficiency.
a. Approximate the pump's capacity if impeller size is increased to 200 mm.
b. Approximate the pump's capacity if pump speed is increased to 3450 rpm.
c. Approximate the pump's total dynamic head if impeller size is increased to 200 mm.
d. Approximate the pump's total dynamic if pump speed is increased to 3450 rpm.
e. Approximate BHP if impeller size is increased to 200 mm.
f. Approximate BHP if pump speed is increased to 3450 rpm.
