A system consisting of 1 kg of H2O undergoes a power cycle composed of the following processes: Process 1–2: Constant-volume heating from p1 5 5 bar, T1 5 1608C to p2 5 10 bar. Process 2–3: Constant-pressure cooling to saturated vapor. Process 3–4: Constant-volume cooling to T4 5 1608C. Process 4–1: Isothermal expansion with Q41 5 815.8 kJ. Sketch the cycle on T– and p– diagrams. Neglecting kinetic and potential energy effects, determine the thermal efficiency

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?
