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 ℃ well temperatures. According to the heat of the reversible heat machine at 47 ° 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

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
