3. a) Butane gas (C4H10) is burned completely with 20 percent excess air during a steady-flow combustion process. The fuel and air enter the combustion chamber at 25°C, and the products leave at 1500 K. The molecular mass unit for air is given as 29. By applying the law of thermodynamics on to the combustion process, calculate the: i. air-fuel ratio. ii. heat transfer for this process.
