An A/C plant is designed for a room with the following conditions: outdoor conditions 40 F db / 60% r.h., required
indoor conditions 70 F db / 50% r.h., amount of air circulation 15 ft^3/min/person, room capacity 50 people. The
required condition is achieved first by heating and then by adiabatic mixing. Show the pro cess on an e-version of
a psych-chart, and thus determine the following:
a. Heating capacity of the coil (BTU/min)
b. Capacity of the humidifier (lbm/min)
