Water is contained in a piston-cylinder assembly undergoes four processes separately, all started from an initial state where the pressure is p1, the temperature is t1, and the specific volume is v1:
process 1→2: constant temperature (isothermal) to p2 = 2p1; process 1→3: constant specific volume to p3 = 2p1;
process 1→4: constant pressure (isobaric) to v4 = 2v1; process 1→5: constant temperature (isothermal) to v5 = 2v1.
draw a p-v diagram and a t-v diagram for the water including the saturated liquid line and the saturated vapor line (dome).
the initial state (state 1) is at the saturated vapor state, note down state 2, 3, 4 and state 5 on both diagrams, and draw all processes (process 1→2, 1→3, 1→4 and 1→5)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
