Atwo-stage air compressor operates at steady state, compressing 10 m^3/min of air from 100 kpa. 300 k, to 1200 kpa. an intercooler between the two stages cools the air to 300 k at a constant 5. pressure of 350 kpa. the compression processes are isentropic. calculate the power required to run the compressor, in kw, and compare the result to the power required for isentropic compression from the same inlet state to the same final pressure. draw the schematic, the p-v, and the t-s diagrams.

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?

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed. gi) ifn 1, what will happen to the material when transformed material when
