We have two noise sources and an RMS voltmeter. We measure the RMS values and they are 3V and 5V. We would like to determine the correlation coefficient. Putting the two noise sources in series produces a noise with 4V effective value. a. Calculate the crosscorrelation coefficient at this arrangement.
b. Both uncorrelated noises must have 1 V rms amplitude.

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.
