Presume you went into the lab and completed a GC analysis of distillates obtained from the distillation experiment. You have analyzed three chloroform:toluene mixtures by gas chromatography using a non-polar column. In the distillation lab, a total of 15 ml of the 50:50 starting material was placed in the distillation pot, and four, 3 ml fractions were collected for simple and fractional distillation. The first sample analyzed is approximately 50:50 starting material used in the distillation (undistilled mixture). The second sample analyzed is the second fraction collected during a simple distillation, and the third sample analyzed is the second fraction collected during a fractional distillation. You wish to see how the percentage of each component varies in each sample. Required:

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.
