3. Mr. G's phone's battery runs out on a road trip in the middle of Arizona. (Great place to be lost right?) He heads 40mi south and 82mi east before getting turned around and heads 19mi west and 97mi north.
Finally he remembers he has a phone charger and starts charging his phone. Identify how far he's gone
and how much farther he needs to go if he needed to go 345mi east and 162mi south from his starting
position

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

Which describes increasing the efficiency of energy resource
