Air enters a window air conditioner at 1 atm, 30 °C, and 80% relative humidity at a rate of 10 cubic meters per min, and it leaves as saturated air at 14 °C. Part of the moisture in the air which condenses during the process is also removed at 14 °C. Determine the rates of heat and moisture removal from the air. (Ans: -506 kJ/min)

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
