The frequency-domain transfer function (or frequency response) of a circuit is given as: HW= (jw) + 512 / (jw)2 +32(jw) + 256
If Vin(t) = 7 + 5sin(8t – 75°) + 10 cos(16t + 15 determine Vout(t). To earn partial credit, you will need to show intermediate work for each term of the input.

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.
