Q2: Ambient air enters a cooling coil at 24°C db-temperature and 50% relative humidity with a dry air mass flow rate of 0.9 kg/s. The air leaving the cooling coil at 9°C is reheated to 13°C and 70% relative humidity. The pressure is constant at 101.3 kPa. Determine (i) the dew-point of the ambient air, (ii) the rate of moisture removal in the cooling coil, (iii) the refrigeration capacity of the cooling coil, and (iv) the heat input rate of the heating coil. Compare the results obtained using ideal gas expressions with those obtained using the psychrometric chart. (v)
