25 pts Find the voltage across the capacitor, VC1(t). There are two spaces for you to fill in to give the value of C1 (in Farads) and the value of R4 (in ohms) before you start the problem. You MUST choose an integer 1-9, for every space you see. For example, for R4 if I choose 1 for the first space and 2 for the second space, the value of R2 is 1.2K ohms.

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.
