The atmosphere of jupiter is essentially made up of hydrogen, for which the specific gas constant is 4157j/(kg-k). the acceleration of gravity of jupiter is 24.9m/s^2. assuming an isothermal atmosphere with a temperature of 150k, and assuming that jupiter has a definable surface, calculate the altitude above that surface where the pressure is one-half the surface pressure.

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.
