An air handling unit at the top of a Riyadh government office is equally mixing hot ambient summer air at 50C

An air handling unit at the top of a Riyadh government office is equally mixing hot ambient summer air at 50C and 30 %RH with the recycled cold air from inside the building at 25C dry bulb temperature and 20C wet bulb. The air is then passed through a cooling coil whose outside surface temperature is at 5C. A) Sketch the processes on the psychometric chart provided? B) At 80% cooling coil efficiency, find the cooling power needed by the cooling coil if the cooled air mass flow rate is 10kg/s? C) Find the amount of condensate produced by the air as it passes through the cooling coil?
