Water as saturated liquid at 1 bar enters a pump operating at steady state and is pumped isentropically to a pressure of 50 bar. Kinetic and potential energy effects are negligible. Determine the pump work input, in kJ per kg of water flowing, using (a) the integral of -vdp and, (b) an energy balance. Obtain data from Tables A-3 (Links to an external site.) and A-5 (Links to an external site.), as appropriate. Compare the results of parts (a) and (b), and comment.
