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...
