Calculate the explicit form of the function h'(x',y') in problem (2). note that you first have to invert the coordinate transformation to calculate r(x',y) and y(x',y) b) calculate v'h'(x',y') by differentiation. c) what are the coordinates (z,, ,%) of the campsite c in system s, ? d) what is the value (i. e. what are the components) of v'h' at campsite c, using your expression from part (b)? e) how does your answer in part (d) compare with your answer in problem (20)?

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.
