- Gaseous combustion products with the molar analysis of 15% CO2, 25% H2O, and 60% N2 enter an engine’s exhaust pipe at 1100 F, 1 atm and are cooled as they pass through the pipe, to 125 F, 1 atm. Determine the heat transfer at steady state, in Btu per lb of entering mixture.A 1.25 mole sample of an ideal gas is expandedfrom 320. K and an initial pressure of 3.10 bar to a finalpressure of 1.00 bar, and CP, m = 5R/2. Calculate w forthe following two cascs:Condition: The expansion is isothermal and reversible.A certain mechanical device with a mechanism similar to a piston contains a certain amount of gas. Upon compression from 30 L to 10 L, the gas released 450 J of heat. Experiment shows that the external pressure of the mechanical device is given by:Pext = AsinV + BcosV + CsinhV + DcoshVWhere:A = 100B = 80C = 1x10⁻²⁵D = 5x10⁻³⁰sin = sine functioncos = cosine functionsinh = hyperbolic sine functioncosh = hyperbolic cosine functionV = in litersPext = in atmDetermine the change in internal energy of the system in kilojoules.TIP: usually, expressions involving trigonometric functions are in radians.
