Anair-conditioning system operates at a total pressure of 1 atm and consists of a heating section and a humidifier that supplies wet steam (saturated water vapor) at 100° C. Air enters the heating section at 10°C and 70 percent relative humidity at a rate of 35 mP/min, and it leaves the humidifying section at 20°C and 60 percent relative humidity. Determine (a) the temperature and relative humidity of air when it leaves the heating section, (b) the rate of heat...

Air enters a heating and humidification system at 5◦C, 50% relative humidity. The air first passes over a heater, and is then humidified with steam. The steam is supplied at 200 kPa pressure and 300◦C. The air leaves the system at 30◦C, 60% relative humidity. (a) Determine the heat transfer to the air, per unit mass dry air. (b) Determine the temperature and relative humidity of the air leaving the heating section (i.e., prior to the humidification section). (c) Determine...

supplies An air-conditioning process consists of a heating section followed by a humidifier that saturated steam at 100°C. Air enters the heater at 10°C and 70% RII at a rate of 35 m3/min. The air leaves the humidifier at 20°C and 60% RH. The system operates at a barometric pressure of 1 atm. Determine: a) the temperature and RH% of the air leaving the heater, b) the rate of heat transfer in the heater, and e) the rate of water...
