Problem 15.10: Liquid octane (CsHis) enters a steady-flow combustion chamber at 25°C and 1 atm at a rate of 0.35 kg/min. It is burned with 50 percent excess air that also enters at 25°C and 1 atm. After combustion, the products are allowed to cool to 25°C. Assuming complete combustion and that all the H2O in the products is in liquid form, determine (a) the heat transfer rate from the combustion chamber, (b) the entropy generation rate, and (c) the...
Propane enters an insulated combustion chamber at 25°C, 1 atm

Octane gas at 25 C and 118 kPa enters a combustion chamber at a rate of 0.09 m /min. The fuel is burned completely with 10 kg/min of dry air which enters the chamber at 22oC and 118 kPa. After combustion, the products are allowed to cool to 37oC and 118 kPa. The heat released by the combustion process is absorbed by another system which is at 460 K. If the surroundings are at 25oC, determine: (a) The heat transfer...

Propane is fed to a combustion chamber at 25°C with pure oxygen. The products exit the reactor as gases, except the water, which is a liquid at 88°C. Assume a constant heat capacity of CO2 equal to 37.35 J/mol-K. If the propane is fed at 200 mole/s, determine the flow rate of O2 entering the reactor in SLPM if the reactor is adiabatic

a) The overall heat transfer coefficient of a steady flow combustion chamber with a 2 m 2 surface area is determine to be 0.5 kW/(m 2-K). Propane is burned with 100% theoretical air, both at 25°C and 100 kPa. Predict the temperature of the products for a propane mass flow rate of 0.2 kg/s. We will assume that the temperature to which the heat transfer occurs will be the ambient temperature, which is the same as the inlet temperature (Hint:...
