Amass of 5.5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 101.325 kpa. initially, 2.3 kg of the water is in the liquid phase and the rest is in the vapor phase. heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kpa. heat transfer continues until the total volume increases by 21 percent. determine: a) the initial temperature (c), b) the final temperature (c), c) the specific volume of water when the piston first starts moving (m3/kg), and d) the work done during this process (kj).

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.
