Moist air enters a control volume operating at steady state witha volumetric flow rate of 3500 ft3/min. The moist air enters at 120°F,1.2 atm, and 75% relative humidity. Heat transfer occurs through asurface maintained at 50°F. Saturated moist air and condensate exitthe control volume, each at 68°F. Assuming Wcv = 0, and kinetic andpotential energy effects are negligible, determine: a. the mass flow rate of condensate, in lb/min.
b. the rate of heat transfer, in Btu/min.
c. the rate of entropy production, in Btu/R - min.
d. the rate of exergy destruction, in Btu/min, for T0 = 50 degrees F.
