4r-134a enters the condenser of a residential heat pump at 800 kpa and 50Β°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3Β°c. the refrigerant enters the compressor at 200 kpa superheated by 4Β°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)

Suppose that f : rn β rm and that a β k, where k is a connected subset of rn . suppose further that for each x β k there exists a Ξ΄x > 0 such that f(x) = f(y) for all y β bΞ΄x (x). prove that f is constant on k; that is, f(x) = f(a) for all x β k
