Space air at 20°C DBT and 50% RH is mixed with outdoor air at 45 °C DBT and 28 °C WBT in the ratio of 4:1. The mixture is passed through a cooling coil whose temperature is maintained at 8 °C and whose bypass factor is 0.25. Find the following: (a) Condition of air entering the coil. (b) Condition of air leaving the coil. (c) If 200 kg/min of air is supplied to the room, find the cooling load of the coil.
