An ideal diesel cycle has a maximum cycle temperature of 2000°c. the state of the air at the beginning of the compression is p1 = 95 kpa and t1 = 15°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 the power produced by this engine when it is operated at 1600 rpm. use constant specific heats at room temperature.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
