-cache-control=pri 120 points) A turbine at steady-state has inlet conditions of T, Pi and discharges conditions of Tz, P. Assuming ideal gases, determine the molar W, Wideal, Wiost, and Sa when T=300 K, T=460 K, P=8 bar, T=368 K, P=1.6 bar, and Cp/R=10/2.
2(30 points) Propane gas at 100C is isothermally compressed from 1 bar to 10 bar. Find H and S. (For data, use the properties of pure species table and the heat capacities of gases in the ideal-gas state table.) The Pitzer Correlation values for residual properties are given as: BO B1 dB/dTr -0.333 -0.0266 0.6594 0.6889.
3) 15 points) 2 kmol/hr of liquid n-octane (species 1) and 5 kmol/hr of liquid iso-octane (species 2) are mixed. The mixing process occurs at constant T and P; mechanical power requirements are negligible.
a. Use an energy balance to determine the rate of heat transfer (J/s).
b. Use an entropy balance to determine the rate of entropy generation (W/K).
4) (35 points) Consider the following chemical reaction: CHg + COg > CHCHOg. Reactants are fed at equimolar concentrations. An additional feed of nitrogen at 4 mols per CO is fed to control the rate of reaction via heat absorption as an inert. The reaction takes place at 260C and 100 bar. Under these conditions, the system behaves as an ideal solution (NOT ideal gases).
Determine the following:
a) Equations for all components in the final mixture as functions of extent of reaction.
b) The final equilibrium concentrations for all components.
Note: You must state and justify all assumptions.
