P-7.188 Determine the work input and entropy generationduring the compression of steam from 100 kPa to 1 MPa in(a) an adiabatic pump and (b) an adiabatic compressor if theinlet state is saturated liquid in the pump and saturated vaporin the compressor and the isentropic efficiency is 85 percentfor both devices.

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?

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
