Determine the real power, the reactive power, the complex power, the apparent power and the power factor for the load having the following characteristics I 240o A, rms, V 45040o A, rms I  1.5 20o A, V  5000 15o V (All values are peaks) I  200 35o A, V 1500 15o V (All values are RMS)

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
