Hydraulics and Fluid Mechanics in ME
If a pump is handling water and is discharging a certain flow Q at a constant total dynamic head requiring a definite B.H.P., the same pump when handling a liquid of specific gravity 0.75 and viscosity nearly same as of water , the horse power required will be
Energy per kN at outlet of impeller Energy per kN at inlet of impeller
All of these
Suction lift + Loss of head in suction pipe due to friction + Delivery lift + Loss of head in delivery pipe due to friction + Velocity head in the delivery pipe
Work-done per kN of water Losses within the impeller
