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

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
