While the outdoor temperature of a house is 47C, a cooling machine is used to keep a constant temperature of 27C. The total cooling load of the house is 15 kW. The power (electrical power) required for the cooling machine of the unit comes from a reversible heat engine operating between 427 source, 47 ā well temperatures. According to the heat of the reversible heat machine at 47 Ā° C we received 10 kW of heat,
a) Thermal power delivered by the cooling wash to the outside environment,
b) COP value of laundering, c) If the cooling machine is also reversible, what is the calculation of the maximum heat it can absorb from the house

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 180Ā°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 Ā°r, as the water flows through the pump.
