As shown in Fig., a 8 m3 tank contains H2O initially at 207 kPa and a quality of 80%. The tank is connected to a large steam line carrying steam at 1380 kPa, 232°C. Steam flows into the tank through a valve until the tank pressure reaches 690 kPa and the temperature is 204°C, at which time the valve is closed. Determine the amount of mass, in kg, that enters the tank and the heat transfer between the tank and its surroundings, in kJ.

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?

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
