Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An air-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 32 m /min, and it leaves the humidifying section at 20°C and 60 percent relative humidity. Use data from the tables. Sat. vapor 100°C Heating coils Humidifier 10°C Air 20°C 70% 60% ymYmin P=1 atm Determine the temperature and relative humidity of air when leaves the heating section. The temperature is °C. The relative humidity is %.

During humidification process, __________ increases. (A) Wet bulb temperature (B) Relative humidity (C) Dry bulb temperature (D) Specific humidity

Air enters an evaporative cooler at 1 atm, 40°C, and 20 percent relative humidity at a rate of 7 m³/min, and it leaves with a relative humidity of 90 percent. Use data from the psychrometric chart. 1 atm 40°C 20% Air Water mw K K Humidifier √2=90% Problem 14.095.b - Evaporative Swamp Cooler Determine the required rate of water supply to the evaporative cooler. The required rate of water supply to the evaporative cooler is kg/min.
