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.

Air enters an air conditioning duct measuring 1 f t by 2 f t with a volume flow rate of 1000 f t3/min. The duct supplies three classrooms through ducts that are 8 in. by 15 in. Find the average velocity in each duct. Answer should be 8.33 f t/s; 6.67 f t/s
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...

1. Air at latm, 15C and 70% relative humidity and volumetric flow rate of 10m /min is first heated to 19C in a heating section and then humidified by introducing water vapor. The air leaves the humidifying section at 24C and 65% relative humidity. Determine: a) The mass flow rate of steam added to the air. b) The heat flow rate transferred to the air in the heating section Heating coils 100.000 1 atm T1 = 15°C T3 = 24°C...
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.
