(Bernoulli/continuity/Pitot tube) Two Pitot tubes and two static pressure taps are placed in the pipe contraction shown in the figure below. The flowing fluid is water, and viscous effects are negligible. Determine the two manometer readings, h and H. V=2.2 ft/s h= H= 6.3 in. Air SG= 1.10 ft •ft H 3.5 in. h
Determine the gauge pressure at the center of pipe B in kilopascals. Mercury (S = 13.6) is the fluid in the manometer while oil (S = 0.93) is the fluid flowing in the pipe. Oil Mercury +B 0.2 m 0.02 m
Example 7: The figure below shows a complex manometer. Calculate: 1. The gauge pressure of the air in the tube (2943 N/m²). 2. The gauge pressure at A (20718.72 N/m²). 3. The absolute pressure at A if the atmospheric pressure is 105Nm2 (120718.72 N/m²). s.g.= 0.90 S.g.= 2.94 B Air 0.6m 0.3m D FU 0.8m Water Density of water = 1000 kg/m³.
Q-4 The apparatus shown in the figure is used to measure the velocity of air at the center of a duct having a 10 cm diameter. A tube mounted at the center of the duct has a 2 mm diameter and is attached to one leg of a slant-tube manometer. A pressure tap in the wall of the duct is connected to the other end of the slant-tube manometer. The well of 10 cm p = 150 kPa the slant-tube manometer is sufficiently large that the elevation of the fluid in it does not change significantly when fluid moves up the leg of T= 20°C the manometer. The air in the duct is at a temperature of 20°C, and the pressure is 150 kPa. The manometer liquid has a specific gravity 30 of 0.7, and the slope of the leg is 30°. When there is no flow in the duct, the liquid surface in the manometer lies at 2.3 cm on the slanted scale. When there is flow in the duct, the liquid moves up to 6.7 cm on the slanted scale. Find the velocity of the air in the duct. Assuming a uniform velocity profile in the duct, calculate the…

Water is flowing through a venturimeter shown. The difference in pressure between Point 1 (D = 4cm) and Point 2 (D = 2cm) is measured using open tubes. If h is 50cm, solve the velocity of flow at Point 1. h O 0.81m/s O 0.88m/s 2.02m/s O 1.29m/s
A U-tube manometer is connected to a closed tank containing air and water as shown in the figure below. At the closed end of the manometer the air pressure is 17 psia. Determine the reading on the pressure gage for a differential reading of 6 ft on the manometer. Express your answer in psi (gage). Assume standard atmospheric pressure and neglect the weight of the air columns in the manometer. Assume Pair = 17 psia, h₁ = 3 ft, h₂ = 6 ft. Pgage = psi -Closed valve -Air pressure = P Gage fluid (y = 90 lb/ft³) air Air Water Pressure gage
