Pressure cookers work on the simply principle that food cooks more quickly at a higher temperature. assuming that the water in the pressure cooker is a saturated mixture with an absolute pressure of 500 kpa, determine the required weight of the vent cap if the release vent area is 4 mm2. (assume that the cap is in equilibrium.) what is the internal temperature?

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?

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
