SOLVED PRACTICAL PROBLEMS in
The radius of the wide part of the tube is 1. Determine the height difference that stabilizes between the surfaces of the mercury in U-tube. The cause of height differences is the separate air pressure above its surface. In the left arm the pressure air p 1 is higher and is pushing the mercury lower into the tube. On to the contrary the pressure air p 2 is lower in the right arm and the mercury can rise higher. Examine the size of the pressure in the lower level of the surface h 0. Arms of the U-tube represent communicating vessels and so the sum of the hydrostatic pressure and the air pressure in both arms must be equal in low surface level h 0.
Tapless Venturi Flowmeter
Venturi Meter is a device in which pressure energy is converted into kinetic energy and it is used for measuring the rate of flow of liquid through pipes. In the pipe, fluid is flowing so first it enters into a converging cone then Thorat and then Diverging Cone. When water flowing through this cone the area is decreasing, therefore, the speed of flowing water increases and pressure decreases. When water flowing through this cone the area remains constant therefore the speed of flowing water and pressure remains constant. When water flowing through this cone the area is increasing, therefore, the speed of flowing water decreases and pressure decreases. After throttling there again a diverging cone diffuser which restores the pressure as nearly possible to the actual value. By this, we can easily determine the volume flow rate with the help of the U-Tube Manometer which is shown in the above diagram, by finding the pressure difference between section 1 converging section and section 2 which is throat.

Problem 13 The accompanying figure represents the longitudinal view of a Venturi meter, a device designed to measure the flow of water in pipes. If the throat of the of the meter is 6 in. Follow iMATHalino. Skip to main content.

Lindsay, I. The Venturi meter is commonly used in combination with other sensors for the measurement of gas fraction and water cut as part of a multiphase flow meter system for the measurement of oil, water and gas flowrates. The Venturi differential pressure signals are generally interpreted using empirical corrections to a momentum equation to give a solution for volumetric flowrate.
Thus, the solution of many problems in hydrodynamics boils down to a solution of the. Laplace equation. The problem is well-posed, and there is.
