4r-134a enters the condenser of a residential heat pump at 800 kpa and 50Ā°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3Ā°c. the refrigerant enters the compressor at 200 kpa superheated by 4Ā°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (Ļ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
