A pressurized tank contains water with some air above it. As shown on figure below. Multi-fluid manometer is used to determine the pressure at the air-water interface If hi= 0.7 m, hz= 0.4 m, h3= 0.55 m and ha 0.85 m. Also, specific gravity of water= 1 and specific gravity of crude oil = 1.8 and specific gravity of mercury = 12.5 and specific gravity of shale oil = %3D 2.5 Determine the absolute pressure at point 5 in Pascal unit. [Given: g= 9.81 m/s? and atmospheric pressure 101300 Pa] %3D %3D Mercury S.G. 12.5 Water S.G. 1 Crude oil S.G. 18 Shale oil SG. 25

Q03

The Venturi meter shown in the sketch below, contracts the flow down to one quarter of its original area. Cold air at 0 deg C flows in the pipe through the Venturi meter. The velocity of the air upstream of the Venturi meter  is equal to 40 ft/s and the pressure at the same point is equal to 30 psia. What is the manometer reading if the fluid of the manometer is water with density 1000 kg/m3 .  Assume that the air behaves as an ideal gas with molecular weight equal to Mw=29 kg/kmol and constant density evaluated at upstream conditions. Use Bernoulli's equation for your calculations.  please respond asap!
