Performed by taking a sample of the mother’s amniotic fluid which is the clear‚ pale‚ yellow fluid that surrounds and protects the baby (Baby Center: "Amniocentesis"‚ 2005). The first reported case of amniocentesis was in 1877 by Prochownick‚ Von Schatz and Lambl. That particular procedure was Tran abdominal amniocentesis and performed during the third trimester of pregnancy. Fuchs and Riis reported the first use of amniotic fluid examination in diagnosis of genetic disorders in

power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump. The energy created by the pump is kinetic energy according the Bernoulli Equation. The energy transferred to the liquid

open end pointing directly towards the fluid flow. As the fluid flows in the tube‚ it becomes stagnant since there is no direct opening at the other end for it to exit from. As the inert fluid rises‚ it creates a pressure of its own. This pressure is equivalent to the dynamic pressure‚ which can be seen as the kinetic energy of the fluid per unit weight. F.X. Pitot originally used this device to analyze the pressure created by the stagnating fluid at the other end of the tube. He did this

engaged in vigorous physical activity? Include in answer: * All of the fluids in your body and all of the fluids produced by your body are mostly water. * These fluids have salts (primarily NaCl) dissolved in the water‚ but the concentration differs: | Amount of Na+ per liter | Fluids in your body (e.g. blood plasma) | | Sweat | | Sports drink | | * Notice that sweat is less salty than the fluids in your body‚ so when you sweat you are losing more water than salt. Consequently

flow meter from different typical methods of measuring the discharge of an incompressible fluid. This can be identify by measuring the flow rate and the head loss with later to be compared to the different flow meter which is venture meter‚ orifice meter and rotameter. INTRODUCTION The objectives of this experiment are to demonstrate the characteristics of some various commonly used methods of measuring fluid flow rates and to identify the head losses associated with each flow measuring apparatus

of venturi to enter into the diverging section‚ their is a negative pressure gradient i.e‚ in layman terms fluid is trying to flow from low pressure region to high pressure region according to Bernoulli equation. In this adverse pressure gradient‚ there is boundary layer separation‚ in simple terms‚ the fluid leaves the surface of the wall. Due to this there can be energy loss or the fluid can’t recover the pressure fully leading to head loss. So if divergent section is long that means more gradual

composed of explosion-proof motor‚ speed reducer‚ motor base and blade. The connection between motor and speed reducer‚ speeder reducer and impeller shaft is achieved by steel coupling. The impeller is welded by four blades. The impeller makes the fluid in vortex motion and improves the agitation effect. The pallet among the vanes can prevent solid particles in mud from depositing around the lower vanes after shutdown‚ which reduces the moment of resistance of deposits against the vanes when starting

Smart System or Structure What is a Smart Structure? A smart structure is a system containing multifunctional parts that can perform sensing‚ control‚ and actuation; it is a primitive analogue of a biological body. Smart materials are used to construct these smart structures which can perform both sensing and actuation functions. If truly smart‚ these intelligent systems can determine their present state‚ decide what is the optimum or more desirable state and carry out an appropriate
