A200-l tank (see fig. p4.107) initially contains water at 100 kpa and a quality of 1%. heat is transferred to the water, thereby raising its pressure and temperature. at a pressure of 2 mpa, a safety valve opens and saturated vapor at 2 mpa flows out. the process continues, maintaining 2 mpa inside until the quality in the tank is 90%, then stops. determine the total mass of water that flowed out and the total heat transfer.

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?
