It is desired to pump 600 m3 /h of liquid ammonia (ρ = 607 kg/m3 ) at a speed of 2500 rpm and a pressure rise of 1000 kPa.
(a) Determine the type of pump best suited for this duty.
(b) Using the appropriate dimensionless pump characteristic curve, find the diameter and number of stages required to meet the pumping requirements.
