Water is pumped from one large reservoir to another at a higher elevation. If the flow rate is 2.5 ft3/s and the pump delivers 14 hp, find the energy loss associated with pumping from section 1 to section 2

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
