Apumo set at an elevation of 2015 feet draws 4.200 gpm of water from a reservoir with a water surface elevation of 2030 feet. an 14-inch cmlcp pipeline (f 0.029) is selected as the suction header (the pipe that runs from the reservoir to the pump). the suction header is 25 feet long and has a rounded entrance (k = 0 25) two 45-degree bends (k-o 20, if the temperature of the water is 80° f, the net positive suction head available (npsha) is most nearly

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?

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
