A pneumatic lift consists of a vertical cylinder with aradius of 10.0 cm. A movable piston slides within the cylinder atits upper end and supports a platform on which loads are placed. Anintake valve allows compressed air from a tank to enter the cylinder,and an exhaust valve allows air to be removed from the cylinder. Ineither case the rate of air transfer is sufficiently low that the temperaturein the cylinder remains constant. When neither valve is activated,the cylinder is airtight. The piston and platform together have a massof 50.0 kg, the temperature is 20.0C, and the pressure outside thecylinder is 1.00 atm. There is 1.00 mol of air in the cylinder and no load on the platform. What is the height h between the bottom of the piston and the bottom of the cylinder?

Calculate the mean free path of air molecules at a pressure of 3.50×10^-13 Pa and a temperature of 300K.
A turbojet is flying with a velocity of 900 ft/s at an altitude of 20,000 ft, where the ambient conditions are 7 psia and 10°F. The pressure ratio across the compressor is 13, and the temperature at the turbine inlet is 2400 R. Assuming ideal operation for all components and constant specific heats for air at room temperature, determine the pressure at the turbine exit.
