3. in a very hot and dry workplace outside air can be drawn in through water spray, and the air is cooled by the heat removed to evaporate the water (evaporative cooling). the data taken before and after installation of such an evaporative cooling system are given below: before installation after installation td (0c) 32.8 29.4 tg (0c) 46.1 35.0 twb (0c) 24.2 24.4 calculate the wet bulb globe temperature before and after installation of the system. also explain why dry bulb temperature (td) and globe temperature (tg) decrease while wet bulb temperature (twb) remains almost unchanged.
