Question

1. 20 kg/s of propane is burned with 50% excess air. Both streams are at 100^oC when entering the combustion chamber. 80% of the propane is burned and 90% of the burned propane goes to CO₂ and the remainder to CO. If the gases exit the combustion chamber at 1300^oC what is the rate of heat production? (Note: All the species are gases. Use mean heat capacities or the first term of the cp expression for this problem)

Answer 1

Almost all type of combustion reaction are solve by Hess cycle law you just need to balace the unit and maa as well as material balance plays a important role here.In this solving problem because there is lack of data like standard heat of formations or components and specific heat data i solve the important needs which required there if we get the data then just putting those all in last equation we can get the solution.
