1. Air at a rate of 1000cfm is cooled from 80°Fdb and 70°Fwb until it is saturated at 55°F. Determine the amount of maisture removed (Ib/min), sensible heat removed (BTU/min), total heat removed (BTU/min), and the sensible heat factor. 2. Outdoor air initially at 30°Cdb and 25°Cwb, is mixed with room air at 22°C and 50%RH. The mixture is to consist of 75% room air and 25% outdoor air. Determine the resulting dry bulb temperature and wet bulb temperature.

Question

Air at a rate of 1000cfm is cooled from 80⁰Fdb and 70⁰Fwb until it is saturated at 55⁰F. Determine the amount of moisture removed (lb/min), sensible heat removed (BTU/min), total heat removed (BTU/min), and the sensible heat factor.

1. Air at a rate of 1000cfm is cooled from 80°Fdb and 70°Fwb until it is saturated at 55°F. Determine
the amount of maisture removed (Ib/min), sensible heat removed (BTU/min), total heat
removed (BTU/min), and the sensible heat factor.
2. Outdoar air initially at 30°Cdb and 25°Cwb, is mixed with room air at 22°C and 50%RH. The
mixture is to consist of 75% room air and 25% outdoor air. Determine the resulting dry bulb
temperature and wet bulb temperature.
