MECH 3020 Thermodynamics II: Homework Assignment # 13 1. Methane is burned with 30% excess air in an adiabatic reactor. The reactants enter at 298 K. Determine the temperature of the products. Assume variable specific heats (i.e., use the gas property table and/or the book tables). 2. Propane is burned with air in an adiabatic reactor. The air/fuel ratio is set so that the exiting products

Unformatted text preview: are at 1400 K. Determine the required air/fuel ratio on a mole basis. Assume variable specific heats. 3. For each the previous two problems, use your answers to calculate the effective specific heat of the products. Compare your values to that for air at room temperature and air at the average temperature of the process. Is there a good match? 1...
