It is desired to control the amount of CO in the products of combustion of octane C8H18 so that the volume fraction of CO in the products is less than 0.1 percent. Determine the percent theoretical air required for the combustion of octane at 5 atm such that the reactant and product temperatures are 298 K and 2000 K, respectively. Determine the heat transfer per kmol of octane for this process if the combustion occurs in a steady-flow combustion chamber. Plot the percent theoretical air required for 0.1 percent CO in the products as a function of product pressures between 100 and 2300 kPa.

Ecocity has two potential sources of water supply: groundwater and a small river fed by a mountain spring. The river supports a lot of fish and other wildlife, so the citizens do not want to use any more of it than necessary. Unfortunately, however, ..
The water enters at 1 atm at 10 C and the flow rate through the turbine is 40 m3/s. The water is discharged from the turbine 200 m below the intake at 1 atm and the temperature of the water at the discharge is 10.2 C.
