***Please guys I need it quickly* The following data were obtained during a Perm-Plug laboratory permeability test:
A= 1.36 cm² ,L = 1.3 cm , Kalr = 0.018 cp, Poutlet = 1 atm.

Using the Perm-Plug method, calculate the absolute permeability of the sample.

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.
