Q: 7200 mhr of moist air at 40°C DBT, 22 °C WBT and 95 kpa barometric pressure, flows through on an evaporative air cooler and leaves it at 28 °C DBT and 22 °C WBT. Calculate without using the psychometric Chart: i. The relative humidity before and after the process. ii. Water Consumption in evaporative air cooler. i effectiveness of the air cooler. iv. The latent heat added through the process. v. The sensible heat rejected through the process. Note: P, = P, - Pat A(DBT – WBT) when A=6.66x10+°C
