A U-tube manometer is used to measure the pressure drop of water (density=1000Kg/m3) in a pipe line, which is in excess of atmospheric pressure. The right limb of the manometer contains mercury (specific gravity=13.6) and is opened to atmosphere. The contact between water and mercury is in left limb. Determine the pressure of water in the main line, if the difference in level of mercury in the limb of U-tube is 10Cm and the free surface of mercury is in...
Problems in Fluid Pressure and Pressure Force 1. AU-tube manometer with mercury is connected to two points on an inclined pipe carrying water. There is an elevation difference of 4ft between the lower and upper points. If the mercury level difference between the two sides of the manometer is 20.3 inches, what is the pressure at the lower point in the pipe, if the pressure at the upper point is 17.5 psi? 2. A vertical semicircular disc of 2 m...
Q1 (a) A U-tube manometer is used to measure the pressure differential between two locations in a building ventilation system. If this reads 80 mm H2O, which of the following correctly describes the pressure differential? (A) 0.080 Pa (B) 0.785 kPa (C) 0.785 Pa (D) 80 Pa (b) The specific enthalpy of 0.20 kg of water contained in a volume of 0.06 m3 at 500 kPa is (A) 1686 kJ•kg-1 (B) 2326.8 kJ•kg-1 (C) 2108.5 kJ•kg-1 (D) 2748.7 kJ•kg-1 (c)...
Draw a picture. Show open surfaces, pistons, boundaries, and other features that affect the pressure. Include height and area measurements and fluid densities. Identify the points at which you need to find the pressure. These objects make up the system; the environment is everything else. Determine the pressure at the various surfaces. For a surface open to the air, p0=patmos, usually 1 atm. For a surface covered by a gas, p0=pgas. For a closed surface, p=F/A, where F is the...
