A heating system for an office building uses an adiabatic saturation air washer followed by heating coil. A mixture of 1.2 m3/s of outside air at 5 oC DB and 50 % RH and 6 m3/s of return air at 20 oC DB and 55 % Rh enter the saturator. The mixture leaves with a temperature 1 degree less than saturation. The heating coil heats the mixture to 38 oC. For the mixture leaving the heating coil, determine a) the relative humidity; b) the specific volume; and c) the heat supplied to the coil. (20 points)
