Please sign in or register to post comments. Fluid Mechanics Introduction Video Lecture From Properties of Fluid Chapter of Fluid Mechanics Subject For All Students. . In case of fluid mechanics, we use some specific pressure gauges for measurement of pressure. Definition The study of f1uids in motion, where pressure forces are not considered, is called fluid kinematics and if the pressure forces are also considered for the fluids in motion. See Fig.7.73. As the entry angle is decreased from 90°, the pressure drop decreases. . . fluid mech. . Pressure is a normal stress, and hence has dimensions of force per unit area, or {ML-1 T-2}.

The measurement of Pressure • The Barometer • Manometers • The Bourdon Gauge • Other types of Pressure Gauge Uniform Rectilinear Acceleration Pressure Variation in a variable density fluid and the Standard Atmosphere. The pressure of a fluid in a pipe may be measured by using a glass U-tube containing a heavier liquid which does not mix with the fluid in the pipe. helpful 41 1. . Unit 23 - Fluid Pressure 1. Pressure always acts inward normal to any surface (even imaginary surfaces as in a control volume). Pressure data obtained using underwater probes were correlated with high-speed motion pictures taken of the entries. For incompressible fluids and compressible fluids with M ≤ 0.3, Professional Publications, Inc. FERC Flow and Pressure Measurement . fluid power technology btm2234 chapter 2: fluids pressure and its measurement After completing this chapter, you should be able to; Define the relationship between absolute pressure, gauge pressure and atmospheric pressure Define the relationship between a change in elevation and the change in pressure in a fluid Results indicate that the cavity pressure drop prior to surface closure is an order of magnitude greater than previously assumed.

Fluid mechanics itself is also divided into several categories. Figure shows one of the many types of mechanical pressure gauges in use today. General Energy Equation 8. The local atmospheric pressure is 15 psia. Fluid pressure at the top of the tube (P 1) is lower than the atmospheric pressure (P 2), and it's value corresponds with the hydrostatic fluid column inside the cylinder (, File S1). . . Selection of pressure gauges depends upon the location and type of fluid flow. Pascal’s Law • The intensity of pressure at any point in a fluid at rest, is same in all directions. . FERC FERC. .

Viscosity of Fluid 3. pressure of a fluid stays constant, the gauge pressure of the same fluid will vary as atmospheric pressure changes. . . . Measurement in Fluid Mechanics also features extensive background materials in system response, measurement uncertainty, signal analysis, optics, ﬂuid mechan- ical apparatus, and laboratory practices, which shield the reader from having to . Suppose the pipe contains water, and mercury is used as the measuring liquid. . 15 MEASUREMENT OF PRESSURE The pressure of a fluid may be measured by the following devices: MANOMETERS: The devices used for measuring the pressure at a point in a fluid by balancing the column of fluid by the same and other liquid. Fluid mechanics is a discipline within the broad field of applied mechanics concerned with the behaviour of liquids and gases at rest or in motion. . The undiminished transmission of pressure through a fluid allows precise remote sensing of pressures. Dresser Instruments, Dresser, Inc. Used by permission. Thought Questions

If the pitot tube is to be used to measure the velocity of a liquid in a pipe, then we must adopt some method to know the static pressure head H. For instance, we may use a pitot tube and a vertical piezometer tube and measure the difference of the liquid levels in the two tubes. . FERC FERC. FERC FERC. Forces in Fluids
