A stream of outside air is mixed with a stream of return air in an air-conditioning system that operates at standard atmospheric pressure. The flow rate of outdoor air is 1/4 of the mixture flow rate and its condition is 32°C dry bulb temperature and 23°C wet bulb temperature. The flow rate of return air is 1/4 of the mixture flow rate and its condition is 24°C and 50% relativehumidity. Determine the following properties of the mixture: a) enthalpy b) specific humidity c dew paint temperature d) dry bulb temperature e) specific volume
