pressure drop in a pipe due to surface roughness. This is to be done using a range of flow rates that are laminar‚ turbulent and in the critical zone. Theory The Reynolds number represents the ratio of inertial forces to viscous forces within a fluid flow. This number is calculated using the diameter (D measured in metres) as the length parameter‚ with the viscosity of the liquid (µ in kgm.s)‚ the density (ρ in kgm3) and the flow rate (U in ms): Re = ρUDμ If the Reynolds number is less than

flu like symptoms‚ in some cases people go years without knowing they have this disease because it can take years for the swelling to start to occur and make people aware of it. When people develop elephantiasis is due to both the buildup of lymph fluid and the impaired ability of the lymph to fight infections‚ leaving affected people more susceptible to germs and bacteria. There are several ways you can treat this disease. The ways you can treat it will depend on how far it has progressed such as

centered by the endplates and the annulus fibrosus. The aggrecan synthesized by the nucleus pulposus cells is highly negatively charged that enables the nucleus pulposus to swell by absorbing water. However‚ there are positive cations in the interstitial fluid‚ thus that charges are electrically balanced. In order to the higher concentration of cations‚ the disc undergoes an osmotic pressure (Donnan equilibrium). Subsequently‚ that gives the capacity to attract and absorb water‚ with the respect to the hydrostatic

A silent disease that can strike in the blink of an eye. The disease can be either bacterial or viral. But today‚ I will focus my efforts on a rather known disease called bacterial meningitis. Let me jump right in! Meningitis is inflammation of the meninges caused by a bacteria or virus. It is extremely important to know whether the disease is viral or bacterial‚ because‚ bacterial meningitis is more severe than viral meningitis. Bacterial meningitis can affect all age groups such as newborns‚ infants

systems and water are currently being studied as solvent alternatives. Another actively studied alternative is supercritical carbon dioxide (spCO2). All have potential benefits and disadvantages that need to be considered. [13] Although supercritical fluids are known since the discovery of the critical temperature 175 years ago‚ their use as reaction media for organic synthesis emerged only during the last 1015 years. Especially the use of scCO2 as a solvent for selective extraction and synthesis processes

Pathophysiology of Disease: (Swelling of tissues produced by an obstruction to the lymph flow in an extremity. Results in excessive accumulation of fluid in the interstitial space.) Lymphedema can be classified as primary (congenital malformations) or secondary (acquired obstruction. Swelling in the extremities occurs due to an excessive increased amount of lymph fluid due to an obstruction of lymphatic system. The obstruction may be in both the lymph nodes and the lymphatic vessels. Eventually this will
