a turbo-machine in which work is done to increase the total pressure of the fluid leaving the device. This is achieved by a rotor or impeller‚ which is driven by an external source of power to move a row of blades so as to impart energy to the fluid. A centrifugal fan‚ the focus of this experiment‚ consists basically of three components: an air inlet duct‚ an impeller and a volute casing. The inlet duct conducts the fluid (in this case‚ it is air) into the impeller. The air then passes through a

Prevention really is the best cure. Meningitis is the inflammation of the fluid and membranes that cover the brain and spinal cord‚ known as the meninges. The inflammation is usually caused by an infection of the fluid surrounding the brain or spinal cord. There are three main types of the meningitis infection: bacterial (both infectious and non-infectious)‚ viral‚ and fungal/environmental (including parasitic). Meningitis may develop in response to a number of causes‚ usually bacteria or viruses

1. Introduction The flow of fluid in a pipe under pressure is used to reach many goals. A good knowledge of the fluid flow and pipe pressure at some point along the path of the pipe may facilitate to determine the size‚ capacity and material of the pipe for a system. In engineering and industry‚ the understanding of pipe flow is required for the control‚ transport‚ measure and storage of water or other fluids. When a fluid is flowing through a pipe‚ it exerts a viscous

The solenoid valve is activated at the time of dash pad button “ON”. The compressed fluid (air) goes to the hydraulic cylinder. The compressed air pusses the pneumatic cylinder piston and move

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

the time which is 5 second to collect the amount of the water. At the same time‚ we also observe the characteristic of the flow whether is it laminar‚ transition and turbulent flow. 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
