mechanical seal/gland packings‚bearing ‚etc. Pump is a device that moves fluids (liquids or gases)‚ or sometimes slurries‚ by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift‚ displacement‚ and gravity pumps. Pumps operate by some mechanism (typically reciprocating or rotary)‚ and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources‚ including manual operation‚ electricity

SCIENCE REVIEW ARTICLE Chronic Subdural Fluid Collection in Children Raj Kumar Introduction In the pediatric population‚ chronic subdural fluid collection is group of related condition termed as extracerebral (or extra-axial) fluid collection (1). Chronic subdural fluid collection can present as chronic subdural hematoma or subdural effusion (2). The term subdural hygroma‚ subdural hydroma‚ chronic subdural hematoma and beningn extracerebral fluid collection etc have been used very loosely

pressure‚ velocity‚ and elevation in a moving fluid (liquid or gas)‚ the compressibility and viscosity of which are negligible and the flow of which is steady‚ or laminar. In order to demonstrate the Bernoulli’s theorem Bernoulli’s Apparatus Test Equipment issued in this experiment. THEORY • Velocity of fluid is less fluid • The fluid is incompressible and non- viscous • There is no heat energy transferred across the boundaries of the pipe to the fluid as either a heat gain or loss. •

An examination of fluid dynamics within a centrifugal pump provides appreciation for the need to analyze the pump “one stage at a time.” The importance of individual pump testing is also identified. This paper focuses on the three ESP products in the csLIFT suite‚ csSubmersible‚ csSubsAnalysis‚ and csSubsDesign. Methods are proposed by which the pump‚ motor‚ producing formation‚ and fluids are considered

viscometer. The viscosity measured in a capillary viscometer is not obtained at a defined shear rate. Of several fixes to this problem‚ the simplest is simply to ignore it. This amounts to assuming that the fluid is Newtonian over the entire range of shear rates encountered by the fluid as it passes down the capillary. The Ubbelohde capillary viscometer The most useful kind of viscometer for determining intrinsic viscosity is the "suspended level" or Ubbelohde viscometer‚ sketched below:

mechanism like the carburetor and the atomizer. The study focuses on Bernoulli’s Theorem in Fluid Application. A fluid is any substance which when acted upon by a shear force‚ however small‚ cause a continuous or unlimited deformation‚ but at a rate proportional to the applied force. As a matter of fact‚ if a fluid is moving horizontally along a streamline‚ the increase in speed can be explained due the fluid that moves from a region of high pressure to a lower pressure region and so with the inverse

high forces with low losses‚ thanks to the virtual incompressibility of hydraulic fluids. Pneumatics is usually less efficient‚ though simpler since the "reservoir" in the circuit is the atmosphere. That eliminates return piping and leakage problems. b) Advantages: It uses ’incompressible’ fluid which results in a greater‚ more efficient & consistent work or power output. This is due to the fact that hydraulic fluid molecules are able to resist compression under heavy load hence minimal energy loss
