Question
A pump with an impeller diameter of 300 mm running at a speed of 2950 rev/min delivering 450 L/min of water at a head of 350 kPa is going to be replaced by a geometrically similar spare pump running at a speed of 1450 rev/min delivering the same flow rate and head. Determine the impeller size of the spare pump and the percentage increase (decrease) of power required for the spare pump. OL. 380.1 mm; a decrease of 61.33% OI., 380.1 mm; an increase of 38.77% I. 147.5 mm; an increase of 3.4% IV. 210.3 mm; a decrease of 83.1%
