DANIEL SENIOR ORIFICE FITTING The Daniel Senior Orifice fitting is a fluid measurement device that measures flow based on the differential pressure principle. The Daniel Senior Fitting utilizes a duel chamber design which positions an orifice plate in a flow stream. The orifice plate generates a pressure drop as flow moves though the Daniel Senior Orifice Fitting. By measuring the pressure drop as flow moves through the Daniel Senior Orifice Fitting‚ and using the pressure drop (differential pressure)

saline drilling fluids were utilized. A total of 5.6x105 L of fluids was lost in the subsurface. The fluid was comprised of surface seawater from the sound‚ as the wetting agent mixed with densifying compounds (mainly potassium chloride and small amounts of fourteen other compounds including biodegradable organics). When exploring pristine locations a main goal needs to be minimizing the amount of biological and chemical contamination. Introducing a contaminant such as drilling fluids could negatively

Pascal’s law Pascal’s law or the principle of transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.[1] The law was established by French mathematician Blaise Pascal.[2] Contents [hide] 1 Definition 2 Explanation 3 Applications 4 See also 5 References Definition[edit source | editbeta]

Summary The topic investigated in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine

THEORY: Reynolds number basically determines the transition of fluid flow form laminar flow to turbulent flow. When the value of Reynolds number is less than 2300‚ laminar flow will occur and the resistance to flow will be independent of the pipe wall roughness (e). Meanwhile‚ turbulent flow occurs when the value of

Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow : Hl α V And for turbulent flow : Hl α Vn Where : Hl :is the loss of pressure head .

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
