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.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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?
