ME2320. Extracredit I 1. The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in the figure. Determine the gage pressure of air in the tank if h 1 = 0.2 m, h 2 = 0.3 m, and h 3 = 0.46 m. Take the densities of water, oil, and mercury to be 1000 kg/m 3 , 850 kg/m 3 , and 13600 kg/m 3 , respectively. 2. Windmills slow the air and cause it to fill a larger channel as it passes through the

Unformatted text preview: blades. Consider a circular windmill with a 7mdiameter rotor in a 10 m/s wind on a day when the specific volume of the air is 0.8409 m 3 /kg. The wind speed behind the windmill is measured at 9 m/s. Determine the diameter of the wind channel downstream from the rotor and the power produced by this windmill. Assume the specific volume of air is constant (air is incompressible)....
