What is the head of the pump if the velocity is 4 m/s and the pressure is 90 kPa on the suction side of the pump? b. How much power is required to drive it if the diameter of the suction side is 600 mm? c. If the pump is rated at 120 hp, what is the efficiency of the pump neglecting energy losses in the system? Pj=90 kPa P>=140 kPa Vj=4m/s ♡ Vz=8m/s Suction side Discharge side 600 mum
