Q.1// Moist air at volumetric flow rate of 280 m³/min and pressure (Pa) at (point 1) with DBT=30°C, R.H=50% (where Pa dehumidifier and water vapor condenses. The air exit at (point 2) with saturated moist air at the temperature equal 10°C and moisture content 0.0076 kg/kg.dry.air. The atmospheric pressure equal 1.013 bar and partial pressure of saturated water vapor equal Pss= 0.04246 bar. Determine: (a) specific volume at the pressure of dry air, = Patm -Ps). The moist air passes over a cooling coil with (b) mass flow rate of the dry air, in kg/min, and (c) mass water condensed. Where: P-pressure of dry air, Patm= atmospheric pressure, P,=partial pressure of water vapor.

Transcribed Image Text:Q.1// Moist air at volumetric flow rate of 280 m³/min and pressure (Pa) at (point 1) with
DBT=30°C, R.H=50% (where Pa = Patm -Ps). The moist air passes over a cooling coil with
dehumidifier and water vapor condenses. The air exit at (point 2) with saturated moist air at
the temperature equal 10°C and moisture content 0.0076 kg/kg.dry.air. The atmospheric
pressure equal 1.013 bar and partial pressure of saturated water vapor equal Pss= 0.04246 bar.
Determine: (a) specific volume at the pressure of dry air,
(b) mass flow rate of the dry air, in kg/min, and
(c) mass water condensed.
Where: P=pressure of dry air, Patm= atmospheric pressure, P,=partial pressure of water vapor.
