differential fluid pressure from low and high pressure sources to actuate an electric switch at a pre-set actuation point. Differential pressure switches are commonly employed to control the operation of snap action switches. Flow switch |[pic][pi| |c] | A flow switch is used to sense the flow of a fluid passing through its valve body and to send an electrical control signal to control the switching unit. In many applications‚ it is essential to be able to determine whether fluid is flowing

TITLE: Water Based Drilling Fluid Analysis EXECUTIVE SUMMARY: Analysis of drilling fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and

Many fluids undergo continuous deformation with the application of shearing stress. 2) Define Newtonian fluids If the force flow relation is linear then the fluid is Newtonian . 3) Define Non Newtonian fluids If the force flow relation is non linear then the fluid is Newtonian . 4) Define Kinematic Viscosity. Ratio of absolute viscosity to the density of the fluid. V= µ cm2 /ς sec 5) Define Specific Viscosity. Ratio of absolute viscosity of the fluid to the absolute viscosity

ABSTRACT Reynolds number can be defined as a number of varieties of situations where a fluid is in relative with motion to a surface. This experiment is to observe the behavior of the flow of fluid either it is laminar or turbulent by calculating it’s Reynolds number and the characteristic of the flow. Other than that‚ the range for laminar and turbulent flow can be calculated and the theory that Reynolds number is dimensionless can be proven. The pump is opened to let the water flow. The dye

Introduction: The point in a body at which the resultant pressure acts when the body is immersed in a fluid. The apparatus for center of pressure. Objective: The object of this experiment was to calculate the hydrostatic force a fluid exerts on a submerged plane surface and then compare the experimental hydrostatic force to the theoretical hydrostatic force. Theory: The apparatus defining the physical dimensions‚ this nomenclature will be used throughout this theory. Whilst the theory

particles contained within a column. Generally a packed column is used to bring two phases in contact with one another. Normally one fluid will wet the packing and flow as a film over its surface. The second fluid will pass through the remaining volume of the column. This promotes a high interfacial area between the two phases and a high degree of turbulence between the two fluids. The fluid’s can be liquid or gas‚ and can be entered into the column either at the top or bottom. Figure 1 represents a typically

ABSTRACT/ SUMMARY The objective of this experiment is to determine the characteristics of open-channel flow. The types of flow to be determined are rectangular notch and triangular v-notch. Another objective of the experiment is to determine the discharge coefficients for both notches. The experiment for rectangular notch begins with admitting water to the channel. At this point‚ the water flow must be adjusted by using control valve in order to obtain heads (H). Throughout the experiment‚ five
