Moist air enters a duct at 10 °C, 80% relative humidity, and a volumetric flow rate of 150 m3/min. The mixture is heated as it flows through the duct and exits at 30 °C. No moisture is added or removed and the mixture stays at 1 atm. Determine the rate of heat transfer and the relative humidity at the exit.

If the air in a 12-inch diameter duct with an air flow of 1,500 ft3/min and a velocity of 14 ft/min flows into a 6-inch diameter duct, what are the new flow rate and velocity? What velocity of air would be required to draw toxic vapors into a duct 24 inches away from a 12 inch round duct with an air flow rate of 1,500 ft3/min? Compare the flow rates into a hood that needs to capture a contaminant at...

4. Liquid water at 100°F and 200 gal/min volumetric flow rate enters a cooling tower operating at steady state. Atmospheric air enters with a dry-bulb temperature of 80°F and a wet-bulb temperature of 60°F. Moist air exits the cooling tower at 90° and 90% relative humidity. Makeup water is provided at 80°F. Calculate the mass flow rates of the dry air and makeup water, each in lb/min, versus return water temperature at 80, 90, and 100°F. Ignore kinetic and potential...

1. A building air-condition unit is designed to cool 2500 ft3/min of outside air (95°F, 740 mmHG, 82% relative humidity) to 50°F, thereby condensing a portion of the water vapor. The system then heats the air and sends it to a building at 68°F a) Calculate the rate of water condensation. b) Calculate the volumetric flow rate of air delivered to the building.

Air at 95°F, 1 atm, and 10% relative humidity enters an evaporative cooler operating at steady state. The volumetric flow rate of the incoming air is 1765 ft3/min. Liquid water at 68°F enters the cooler and fully evaporates. Moist air exits the cooler at 70°F, 1 atm. There is no significant heat transfer between the device and its surroundings and kinetic and potential energy effects can be neglected. A. Determine the mass flow rate of the dry air in lbm(dry...
