Pressure Measurements Using Different Devices

Abstract: The purpose of this experiment was to utilize a Bourden Gage, a U-tube manometer and a body of water piezometer to analyze the behavior of a remains placed under force per building block bea, and to test the validity of the hydrostatic cart par. In order to accomplish these ends, the fluids within the system (air, water and mercury) must be considered incompressible. Experimental data upholds the validity of the hydrostatic pressure equation, as both the manometer and piezometer displayed a direct relationship between system pressure and fluid height. An analysis of percent error revealed a discrepancy between the accuracy of the manometer and piezometer. At low pressure, the manometer displayed a 100% error, which trailed off smoothly to a final value of 31% at high pressure. The piezometer, on the other hand, simply fluctuated up and down between 0 and 10% error with no relationship to the pressure level. This could be evidence of a small leak in the manometer which causes a fixed pressure drop, causing a greater percent difference at lower pressures than at higher pressures.

launch and Objective:  Pressure is a measure of force exerted per unit area.  In order to use the principles of fluid statics to analyze pressure in a system, it is helpful to make several assumptions.



 Fluids are take for granted to be incompressible, in other words, they occupy a constant volume and maintain a constant parsimony throughout the experiment.  Pressure on a fluid at rest is assumed to be isotropic at every point, which is necessary to satisfy the zero sum force dimension at a disposed point.  In addition, pressure is assumed to be exerted normal to the contact surfaces at the boundaries of the system.  Pressure in a given system is governed by the following equation:
P = ?gh = ?h (Eq. 1)
where ? is density, g is the gravitational acceleration constant, P is the pressure and h is the height at any given point in the fluid.  Alternatively, the specific gravity (?) of...If you want to go about a full essay, order it on our website: Orderessay
