Reg.no : 5395 Pb # 6: At its optimum point of operation, a given centrifugal pump with an impeller diameter of 500 mm delivers a 4 m3/s of water against a head of (Reg.No/100) m when rotating at 1500 rpm. (a) If its efficiency is 82%, what is the brake power of the drive shaft? (b) If a homologous pump with a diameter of 800 mm is rotating at 1200 rpm, what would be the discharge, head, and shaft power. Assume both operate at the same efficiency. (c) Compute the specific speed of both pumps. What type of pumps are these?
