A piston-cylinder device contains products of combustion from the combustion of a hydrocarbon fuel with air. The combustion process results in a mixture that has the composition on a volume basis as follows: 4.89 percent carbon dioxide, 6.50 percent water vapor, 12.20 percent oxygen, and 76.41 percent nitrogen. This mixture is initially at 1800 K and 1 MPa and expands in an adiabatic, reversible process to 200 kPa. Determine the work done on the piston by the gas, in kJ/kg of mixture. Treat the water vapor as an ideal gas.
Water is flowing through a pipe with a circular cross section at a rate of 5.2 gallons per minute (US GPM). The pipe has an outer diameter of 2.2 inches and an inner diameter of 1.6 inches. What is the average velocity of the flow in the pipe in ft/s..
