Given that diameter of shaft is 1.5 inch and its upper and lower tolerance limits are 0.03 inch and 0.04 inch respectively. The diameter of hole is 1.48 inch with upper and lower limits of 0.03 inch and 0.05 inch respectively. Determine the fit for this assembly. (Justify your answer) (5 points)

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.
