Amount of absorption in a tray tower. an existing tower contains the equivalent of 3.0 theoretical trays and is being used to absorb so2 from air by pure water at 293 k and 1.013 x 10 5 pa. the entering gas contains 20 mol % so, and the inlet air flow rate is 150 kg inert air/h m2. the entering water rate is 6000 kg/h - m 2. calculate the outlet composition of the gas. (hint: this is a trial-and-error solution. assume an composition of, say, y, = 0.01. plot the operating line and determine the number of theoretical trays needed. if this number is not 3.0 trays, assume another value of y 1, and so outlet gas on.)

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.
