An insulated cylinder is divided into 2 parts of 1 m^3 each by an initially locked piston, as shown in figure P5.95. Side A has air at 200 kPa, 300 K, and side B has air at 1.0 MPa, 1000K. The piston is now unlocked so that it is free to move, and it conducts heat so that the air comes to a uniform temperature Ta=Tb. Find the mass in both A and B, and the final T and P

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.
