Agoulds 3196 2x3-10 pump operates at 3560 rpm with a 10" impeller generating a flow of 350 gpm when connected to a particular piping system.

a. find the head increase, power required by the pump and the pump efficiency.
b. using the industrial affinity laws find the new flow rate, head increase and power when operating at 1750 rpm with an 8" diameter impeller. compare your result with data obtained from the pump performance map at 1750 rpm.
c. repeat part b) using the academic scaling laws.
