Alarge heat pump should upgrade 5 mw of heat at 85°c to be delivered as heat at 150°c. suppose the actual heat pump has a cop of 2.5. how much power is required to drive the unit? for the same cop, how high a high temperature would a carnot heat pump have, assuming the same low t?

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
