CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping. Centrifugal pumps are used for

S. Raghavachari Consultant Chennai Abstract Mechanical seals are pieces of engineering marvel. Process industries could meet today’s stringent environmental pollution regulations through the effective sealing of even the most difficult fluids. This paper describes different kinds of seals‚ their design‚ properties and functioning. Effect of various factors like seal balance‚ face pressure‚ temperature and lubrication on performance of seal and probable causes of seal leakage with their

Pressure at bottom greater than at top A substance that is able to take the shape of any container that holds it. If a density is less than that of water (or the liquid it is floating in) acts against buoyant force A buoyant force on an object is equal to the weight of the fluid displaced by the object. occurs when

Department of Mechanical Engineering Indian Institute of Technology‚ Delhi Hauz Khas‚ New Delhi-110016 Abstract Environmental concerns call for the reduced use of cutting fluids in metal cutting practice. Minimum quantity lubrication (MQL) machining is one of the promising solutions to the requirement for decrease in cutting fluid consumption. This paper reports the results of an experimental work to investigate the effect of a well-designed MQL set up on machining constraints like tool forces and

coriolis mass flow meter When there is no flow in the pipe the measuring tube oscillates uniformly. In addition‚ sensors are located at the inlet and the outlet of the tube. These sensors have ability to notice this basic oscillation perfectly when the fluid starts to flow in the measuring tube. Additional twisting is applied on the oscillation because of the liquids inertia. As a result of Coriolis Effect‚ the inlet and the outlet parts of the tube oscillate in different directions simultaneously. These

at the cellular level this will affect the body as a whole. History Claude Bernard (1813-1878): consistency of internal environment is the condition for free life. Internal environment: Immediate surroundings of cells—Intracellular fluid and interstitial fluid provide the medium which baths the cells. Appropriate cellular functioning depends on constancy of this environment. Cellular Homeostasis Cells must maintain a constant internal environment and must be able to reproduce themselves when
