An ideal diesel cycle has a maximum cycle temperature of 850 degrees c and a cutoff ratio of 1.13. the state of the air at the beginning of the compression is p1 = 96 kpa and t1 = 15 degrees c. this cycle is executed in a four-stroke, eight-cylinder engine with a cylinder bore of 10 cm and a piston stroke of 12 cm. the minimum volume enclosed in the cylinder is 5 percent of the maximum cylinder volume. determine thepower produced by this engine when it is operated at 1750 rpm. use constant specific heats at room temperature.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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.

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c.
