Question

Propane gas is used as the fuel in a combustion furnace. The propane is fed into the furnace 25 degrees celcius and 1.1 atm (absolute) at a flowarate of 1000 mol/s and burned with 130% excess air at 250 degrees celcius and 1.2 atm (absolute). The products from the combustion reaction leave the furnace at 900 degrees celcius and 1 atm (absolute).

a) What is the volumetric flow rate of the air fed to the furnace in (L/s)? What is the flowrate in SCFM?

b) Assuming 100% combustion of the propane and that no CO is formed, calculate the volumetric flowrate of the combustion products in L/s.
