Ahydrocarbon fuel cmhn is burned at atmospheric pressure with stoichiometric amount of air as the oxidizer. determine the expression of air fuel ratio, the mole fraction and the combustion products.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

An electrical kettle is made out of stainless steel,weighs two pounds (when empty) with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling.
