Q/ Super-heated vapor enters condenser of a steam power plant at 2 bar and 250 °C. The vapor is condensed at 0.2 bar and 60 °C. Condensed cooling water enters into another streamline at 25 °C and the water exits at 40 °C. The heat is transferred from the condensing steam to the cooling water with no change in kinetic and potential energies. Calculate (a) the ratio of the cooling water mass flow rate to the condensing steam mass flow rate. (b) The specific heat transfer from the condensing steam to the cooling water.

A pump 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 90 lbf/in.² The pump requires 1/25 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. °R. Neglecting kinetic and potential energy effects, determine the temperature change, in °R, as the water flows through the pump. AT = °R

As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40oF, 80 lbf/in2 and is compressed to 160oF, 200 lbf/in2. The refrigerant exiting the compressor enters a condenser where energy transfer to air as a separate stream occurs, and the refrigerant exits as a liquid at 200 lbf/in2, 90oF. Air enters the condenser at 75oF, 14.7 lbf/in2 with a volumetric flow rate of 1500 ft3/min and exits at 110oF. Neglect stray heat transfer and kinetic and potential energy effects, and assume ideal gas behavior for the air.
