Even though has been described as “water on the brain” it is a clear fluid surrounding the spinal cord and brain called (CSF) cerebrospinal fluid. The excessive accumulation of cerebrospinal fluid is an result in an abnormal widening of spaces in the brain called ventricles. The fluid has an effect that helps prevent the vital brain tissue from injury. The fluid is made continuously

Impeller Design‚ Metallurgy of the pumps and type of pumps are largely dependent on the specification of the fluid. Few Considerations to be taken care are Solids to be handled‚ Temperature of fluid‚ Corrosive and abrasive nature of fluid ‚ toxicity of fluid and we should check if the fluid is highly flammable .

The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing from the tap. Varying temperatures and flow rates were used via adjusting the heating component and the control valve respectively to determine the effect each had

MICROENCAPSULATION Microencapsulation: Definition: It is the process by which individual particles or droplets of solid or liquid material (the core) are surrounded or coated with a continuous film of polymeric material (the shell) to produce capsules in the micrometer to millimetre range‚ known as microcapsules. Microencapsulation (Cont.): Morphology of Microcapsules: The morphology of microcapsules depends mainly on the core material and the deposition process of the shell. 1- Mononuclear

jet. The theoretical jet force can be calculated from the principle of linear momentum. The density of water is 1kg/L. The results obtained are to be compared with the theoretical values. To produce mechanical work from fluid under pressure‚ we use the pressure to accelerate the fluid to a high velocity in a jet. The application of this principle can be seen surrounding us. For example‚ water turbines are used to generate power in our country. Another example is that the kinetic energy stored in a jet

Welding Process and Final Weld Shape A computer simulation accurately predicts weld pool fluid flow convection and final weld shape BY M. H. CHO‚ Y. C. LIM‚ AND D. F. FARSON ABSTRACT. The pulsed gas metal arc welding (GMAW-P) process was modeled numerically using a code based on the volume of fluid (VOF) technique‚ chosen primarily for its ability to accurately calculate the shape and motion of free fluid surfaces‚ which is needed for subsequent study of welding phenomena such as bead hump
