A fan within an insulated duct delivers moist air at the duct exit at 35°C, 50% relative humidity, and a volumetric flow rate of 0.4 m3/s. At steady state, the power input to the fan is 1.7 kW. The pressure in the duct is nearly 1 atm throughout. Using the psychrometric chart, determine the temperature, in °C, and relative humidity at the duct inlet.
