Steam at 200psi and 600 of (state 1) enters a turbine through a 3-inch-diameter pipe with a velocity of 10 ft/s. the exhaust from the turbine is carried through a 10-inch-diameter piper and is at 5 psi and 200 of (state 2). assume no heat exchange at the turbine, what is the power output of the turbine? the following state functions are given: h1=1322.6 btu/lbm, h2= 1148.6 btu/lbm, v1= 3.058 ft3/lbm, v2= 78.14 ft3/lbm.

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?
