OK, if you are really clever you might have realized that the bottom of the can is slightly lower in the fluid than the top of the can, and since the pressure gets larger the deeper you go (P g a u g e = ρ g h P_{gauge}=rho g h P g a u g e = ρ g h) the upward pressure on the bottom of the can should be slightly larger than the downward pressure on the top of the can.

3.1 DEFINITION AND MEASUREMENT OF VISCOSITY The behavior of a fluid in flow is very much related to two intrinsic properties of the fluid: density and viscosity. For example, a solid body moving through a gas has to overcome a certain resistance which depends on the relative velocity between fluid and solid, the shape of the solid, the density of the gas and its viscosity. The power required

The product of the process fluid density and its depth from the end of the dip tube to the surface is equal to the pressure, which is monitored by a pressure transducer connected to the tube. Figure 4 depicts a differential pressure level sensor.

height, its pressure and density tend towards zero. As we descend towards the earth, the number of As we descend towards the earth, the number of molecules per unit volume increases, compressed by the weight of the air above.

Flow & Level Measurement ing fluid increases its kinetic energy while decreasing its static energy. It is for this reason that a flow restric- tion causes an increase in the flowing velocity and also causes a drop in the static pressure of the flowing fluid. The permanent pressure loss through a flowmeter is expressed either as a percentage of the total pressure drop or in units of

Fluid mechanics can be sub-divided into Fluid Statics (or Hydrostatics) – the study of ﬂuids at rest – and Fluid Dynamics (or Hydrodynamics), the study of ﬂuids in motion.

Pressure measurement devices such as Inclined Manometer, Bourdon Gauge, Diaphragm Gauge, Bellows, Pressure Transducers, and Electronic Pressure Sensors, are used to measure extreme pressures with high accuracy. For pressure measurement in hydraulics analysis in civil engineering the knowledge of construction and working of these devices is a must.

with a constriction in it, the fluid pressure is lowest at the constriction. In terms of the equation of continuity the fluid pressure falls as the flow speed increases. The reason is easy to understand. The fluid has different speeds and hence different kinetic energies at different parts of the tube. The changes in energy must result from work being done on the fluid and the only forces in

Pressure measurement 3 this practice is discouraged by the NIST.[1] Because pressure was once commonly measured by its ability to displace a column of liquid in a manometer,

To measure larger pressure differences we can choose a manometer with higher density, and to measure smaller pressure differences with accuracy we can choose a manometer fluid which is having a density closer to the fluid density.

Introduction. Pressure measurement and control is the most used process variable in the process control industry many segments. In addition, through the pressure it is possible infer a series of other process variables, like level, volume, flow and density.

After the constricted area, the fluid is passes through a pressure recovery exit section, where up to 80% of the differential pressure generated at the constricted area, is recovered. With proper instrumentation and flow calibrating, the Venturi Tube flowrate can be reduced to about 10% of its full scale range with proper accuracy.

transverse force is erroneously judged as insignificant and its measurement requires a sophisticated instrumentation to be placed in the fluid area, thus to be exposed to high pressure and temperature.

Pressure is defined as force per unit area that a fluid exerts on its surroundings. Pressure, P, is a function of force, F, and area, A: P = F/A. The SI unit for pressure is the pascal (N/m 2), but other common units of pressure include pounds per square inch (psi), atmospheres (atm), bars, inches of mercury (in.

Most of the case, for gauge pressure measurements, mercury is widely used as manometric fluid because it has nonevaporating quality – under normal conditions, sharp meniscus and stable density.

For example, the measurement of blood pressure usually gives the two steady-state values of systolic and diastolic pressure. There is much additional information in the shape of the blood pressure signal, however, which is the reason for the monitors used in critical-care situations.
