Two thousand cfm (1.0 m3/s) of air at an initial state of 60 F (16 C) db and relative humidity of 30 percent is to be heated

Two thousand cfm (1.0 m3/s) of air at an initial state of 60 F (16 C) db and relative humidity of 30 percent is to be heated and humidified to a final state of 110 F (43 C) db and 30 percent relative humidity. Assume sea-level pressure throughout. The air will first be heated followed by adiabatic humidification using saturated vapor at 5 psia (34.5 kPa). Using the psychrometric chart, find the heat transfer rate for the heating coil and the mass flow rate of the water vapor and sketch the processes on a skeleton chart showing pertinent data. Use (a) English units and (b) SI units.
