2. The diameter of the discharge side of a pump is 100and that of the intake pipe is 120 mm. , the pressure gage at discharge read 240 kpa and the pressure and the intake reads 60 kpa if Q=45 of water and the pump efficiency is 0.82 find the power delivered to the pump by the drive shaft the intake of the pump is 350 mm below the discharge side neglect the effects of pre rotation in the entry pipe and assume smooth flow at discharge from the pump
