Oxygen therapy uses various devices to provide oxygen to patients having difficulty getting sufficient amounts from air through normal breathing. Among the devices are nasal cannula, which transport oxygen through small plastic tubes from a supply tank to prongs placed in the nostrils. Consider a specific configuration in which the supply tank (volume = 7.00 ft3) was filled to a pressure of 2100.0 psig at a temperature of -30.0°F. The patient is in an environment where the ambient temperature is...

A closed, rigid tank is filled with water. Initially, the tank holds 1.0 lb of saturated vapor and 7.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

Scuba Tanks: A popular scuba tank is the “aluminum 80,” so named because it can deliver 80 cubic feet of air at “normal” temperature (72°F) and pressure (1.00 atm, 14.7 psi) when filled with air at a pressure of 3000 psi. A particular aluminum 80 tank has a mass of 15 kg when empty. What is its mass when filled with air at 3000 psi?

a) A closed tank of fixed volume initially contains air at 200 kPag (gauge) pressure and 20oC temperature. One (1.0) kilogram of air is added to the tank by an air compressor to bring the tank pressure to 300 kPag and temperature to 32oC. Find the tank volume. Specify any assumptions used. b) To the same tank as above, a gas mixture containing CO and CO2 is added to replace the air. With 2 kg of the gas mixture added,...

A SCUBA tank, an air tank used for breathing under water, is initially filled with gas at a pressure of 2.8x107 Pa and 32 oC. The tank has a volume of 11.5 L. If the tank will continue to provide air until it reaches a pressure of 1.2x106 Pa, how many moles of gas will it provide to a diver diving in water at 10 oC? Give your answer in moles to at least three significant figures. Hint: There will...

One mole of air is compressed from pressure P1 and temperature T1 at constant volume till its pressure is doubled. Then it is expanded reversibly and isothermally to the original pressure, and finally restored to the original temperature by cooling at constant pressure. Sketch the path followed by the gas, on a P-V diagram and calculate the net work done by the gas.
