Extracted text: Problem 1: Air at 45 C (dry bulb) and 10% relative humidity is to be humidified adiabatically to 60% relative humidity. Use the psychrometric chart to estimate the adiabatic saturation temperature of the air. b. Estimate the final temperature of the air and the rate at which water must be added to humidify 15 kg/min of the entering air. а. Problem 2: Air at 50°C with a dew point of 4°C enters a textile dryer at a rate of 11.3 m3 /min and leaves saturated. The dryer operates adiabatically. Use the psychrometric chart to determine the absolute humidity and humid volume of the entering air, and then use the results to determine the flow rate of dry air (kg/min) through the dryer, the final temperature of the air, and the rate (kg/min) at which water is evaporated in the dryer.
