Steam at 300 psia and 700 F enters a nozzle under steady conditions. The mass flow rate is 10 lbm/s. Steam leaves the nozzle at 200 psia with a velocity of 900 ft/s. The nozzle loses heat at the rate of 1.2 BTU per pound of steam flow. Determine the a) Inlet Velocity (inlet area

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?
