Steam at 1 mpa and 600°c enters a well-insulated turbine operating at steady state with a velocity of 50 m/s and exits at 0.01 mpa with a velocity of 100 m/s. the work developed per kg of steam flowing is claimed to be 1050 kj/kg. is this a valid claim? (clearly justify your answer). assume negligible potential energy changes.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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?
