Moist air flow through a duct which contains a heating element. The moist air enters at 95 kPa, 12 C and
(I) = 30%; the flow rate is 6 m3/min. Air leaves the heating element at 25 C. Using a table or curve fit
approach: Find the relative humidity at the exit and the rate of heat transfer (kJ/min) Find t...
