In a supermarket, air at atmospheric pressure and 25 °C is supplied to an air handling unit through a rectangular duct with a cross section of 0.5 m x 0.1 m. The air handling unit will distribute 2/3 of the air to the large shopping area of the supermarket at 25 °C, and it will cool the remaining air to -5 °C and distribute it to a walk-in refrigerator. To avoid frictional pressure losses, the average air velocity in the...

An adult inhales approximately 12 times per minute, taking in about 500 mL of air with each inhalation. Oxygen and carbon dioxide are exchanged in the lungs, but there is essentially no exchange of nitrogen. The exhaled air has a mole fraction of nitrogen of 0.75 and is saturated with water vapor at body temperature, 37°C. If ambient conditions Professor Christina Tang, [email protected] 2 are 25°C, 1 atm and 50% relative humidity, determine what volume of liquid water (mL) would...

Typically, when a person coughs, he or she first inhales about 2.10 L of air at 1.00 atm and 25 ∘C. The epiglottis and the vocal cords then shut, trapping the air in the lungs, where it is warmed to 37 ∘C and compressed to a volume of about 1.70 L by the action of the diaphragm and chest muscles. The sudden opening of the epiglottis and vocal cords releases this air explosively. Just prior to this release, what is...

In class we showed that hot air at atmospheric pressure is less dense than cooler air at the same pressure. Because of this difference hot-air balloons can stay aloft. Assume that you have an air-balloon that has the volume of 500 m3 and the surrounding air is at 100C. You want to lift 250 kg object (in addition to the mass of the hot air that is inside the balloon). What must be the temperature of the air in the...
