Water at p1 = 20 bar, T1 = 400°C enters a turbine operating at steady state and exits at p2 = 1.5 bar, T2 = 260°C. The water mass flow rate is 4000 kg/hour. Stray heat transfer and kinetic and potential energy effects are negligible.
(a) Determine the power produced by the turbine, in kW;
(b) The rate of entropy production in the turbine, in kW/K.

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?
