Air at 7°C enters a turbojet engine at a rate of 16 kg/s and at a velocity of 220 m/s (relative to the engine). Air is heated in the combustion chamber at a rate 15,000 kJ/s, and it leaves the engine at 427°C. Determine the thrust produced by this turbojet engine. (Hint: Choose the entire engine as your control volume.)
A power plant with a nominal rating of 1kW does not actually produce 1kW continuously because its capacity factor C - the fraction of the time that it is actually running at its rated power - is less than 100%. If the capacity factor C = 35%, how much energy will be generated by this power plant over 1 year in MJ?

A four-cylinder, four-stroke, 1.6-L gasoline engine operates on the Otto cycle with a compression ratio of 11. The air is at 100 kPa and 37°C at the beginning of the compression process, and the maximum pressure in the cycle is 8 MPa. The compression and expansion processes may be modeled as polytropic with a polytropic constant of 1.3. Using constant specific heats at 850 K, determine the specific fuel consumption, in g/kWh, defined as the ratio of the mass of the fuel consumed to the net work produced. The air– fuel ratio, defined as the amount of air divided by the amount of fuel intake, is 16.
