At steady state, a power cycle receives energy by heat transfer at an average temperature of 463°c and discharges energy by heat transfer to a river. upstream of the power plant the river has a volumetric flow rate of 67.87 m’s and a temperature of 20°с. from environmental considerations, the temperature of the river downstream of the plant can be no more than 22°c. determine the maximum theoretical power that can be developed, in mw, subject to this constraint.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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?
