A heat pump is used to warm a building in the winter. This system implements an ideal vapor-compression cycle with R-134a as the working fluid. The cycle operates between 200 kPa and 800 kPa, with a mass flow rate of 0.02 kg/s. Determine: (a) the heating load that can be met kW (b) the power input required for this system kW (c) the coefficient of performance (d) the warmest outside temperature at which this particular cycle is unable to operate ∘C

On a average work day more than work place firs are reorted

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.
