An AC load draws 5 kW of power at a lagging PF of 0.8 from a 60 Hz power line. If the effective voltage drawn by the load is 120 Vrms, calculate the value of capacitor needed to correct the given load to a PF of 1. Express your answer in micro-Farads (µF). 1 micro = 10-6

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.
