A centrifugal pump operating under steady flow conditions delivers 2 270 kg/min of water

A centrifugal pump operating under steady flow conditions delivers 2 270 kg/min of water from an initial pressure of 82,470 Pa to final pressure of 275,800 Pa. The diameter of the inlet pipe to the pump is 15.24 cm and the diameter of the discharge pipe is 10.16 cm. What is the work?

During a steady flow process, the pressure of a working substance drops from 200 to 20 psia, the speed increases from 200 to 100 ft/s, the internal energy of a working system decreases to 25 BTU/lb, and the specific volume increases from 1 to 8 ft3/lb. No heat is transferred. Sketch an energy diagram. Determine the work per lb. Is it done on or by the substance? Determine the work in hp for 10 lb/min.
