Determine the adiabatic combustion temperature at constant pressure and at constant volume for two of the fuels of personal choice. Graphically show that this corresponds to the product temperature where the heat of reaction is zero.

What is the efficiency of the most efficient combustion engine? Explain why it is so inefficient. How does the efficiency of an electric motor compare with an internal combustion engine? If this were the selling feature for an electric car, explain why this is terribly misleading.

Consider a rocket that burns steadily. The higher pressure in the combustion chamber, the faster the propellant burns. Why is this? The relationship is such that the higher the pressure, the closer the gaseous flame is to the surface and the more effectively it can transfer heat back to the surface thereby gasifying the propellant quicker. The rate of gas generation, ?_? , can be described by the equation: ?_?=?_1 ?^?, where P is the pressure, and C1 and n...

Small high-swirl direct-injection CI engines have fuel conversion efficiencies which are about 10 percent higher than values typical of equivalent indirect-injection engines. (ID1 engines are used because they achieve higher bmep.) What combustion-system-related differences contribute to this higher efficiency?

An air–fuel mixture enters a constant area combustion chamber at a velocity of 100 m/s a pressure of 70 kPa and a temperature of 150°C. Assuming that the fuel–air ratio is 0.04, the heating value of the fuel is 30 MJ/kg, and the mixture has the properties of air, calculate the Mach number in the gas flow after combustion is completed and the change of stagnation temperature and stagnation pressure across the combustion chamber. Neglect the effects of viscosity and...

What does Boyle's law state about pressure and volume at a constant temperature and a constant...

What does Boyle's law state about pressure and volume at a constant temperature and a constant pressure? Pressure and volume will both increase together or both decrease together. Pressure and volume will both increase as temperature and pressure increase. Pressure increases when volume decreases. Pressure and volume will both decrease as temperature and pressure decrease.
