Q3: An engine produce 750 kW power and uses gaseous C12H26 as a fuel
at 25 C; 200% theoretical air is used and air enters at 500 K. The products
of combustion leave at 800 K. The heat loss from the engine is 175 kW.
Determine the fuel consumption for complete combustion.
Qu 5 Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt% at a position 4 mm into an iron carbon alloy that initially contains 0.10 wt% C. The surface concentration is to be maintained at 0.90 wt% C, and the treatment is to be conducted at 1100°C. Use the data for the diffusion of
carbon into y-iron: Do = 2.3 x10-5 m2/s and Qd = 148,000 J/mol. Express your answer in hours to three significant figures.
