1. Methane, ethane, and propane, all ideal gases, are mixed together in equal parts by mass to create a new "super" fuel gas. Then, it is adiabatically compressed from 40.0°F to 1.75 ft3 at 300. psia, 80.0°F. Determine the work required.
2. A chemical processing facility produces exhaust gases (46.0% N2, 43.0% CO2, and 11.0% SO2 by volume) at a total pressure of 0.320 MPa at 1000.°C. It is proposed that energy be recovered from this gas by expanding it through a turbine to atmospheric pressure. Assuming ideal gas behavior, determine the maximum possible power output per unit mass flow rate for this system.
