Cutting fluid

Meningitis is inflammation of the meninges. These meninges surround the brain and spinal cord which is very dangerous as Inflammation in these areas can affect your whole body and because it to stop working. This can also occur due to injury in the certain parts of your head. Bacterial meningitis is not as common as viral meningitis. But it is more dangerous than viral meningitis, it could even possibly be life-threatening without being promptly treated it can lead to many very serious…

Abstract Background: Hydrocephalus is an abnormal CSF collection in brain cavities, within the cerebral ventricles caused by a blockage in the drainage or insufficient absorption of the fluid [1]. It is categorized either congenital or acquired [1]. Hydrocephalus can be diagnosed by detailed history, physical examination and radiological examination [1]. MRI is considered the method of choice because It allows us to evaluate various parts of the brain and certain associated conditions that may…

Introduction Bernoulli principle is a statement of conservation of energy per unit mass for an ideal fluid in steady motion, where it states the sum of pressure, kinetic and potential energies per unit volume is constant (Munson, et al., 2013). Venturi effect is where the pressure of the fluid decreases which causes its velocity to increase as it passes through a constricted section of a pipe. This is the basis of this report’s investigation. The aim of this investigation is to compare the flow…

Therefore, if the pressure filter is semi blocked (not fully blocked), the flow rate decrease at the orifice makes the pressure at pump will be increased and suddenly, the pressure decreases after pass the orifice. Schaschke (2005) stated that a drop in fluid pressure because the increase in the cross-section causes a reduction in velocity and an increase in pressure. The kinetic energy is decreased and the potential energy which is in a form of pressure will increase simultaneously then, they…

Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

production rate and helps understanding how the flow rate is affected by different parameters (Lund). Additionally, in order for fluid to flow there has to be a pressure gradient. As this pressure gradient increases the fluid flow rate increases as well. The Darcy equation incorporates pressure gradient by a negative sign in the equation. The negative sign indicates that fluid in a high pressure area will flow to an area of low pressure. Pressures are related to extracting hydrocarbon from a…

Multi-stage fracturing is an advanced drilling technology that enhances the production capabilities through maximizing the contact area of unconventional wells with the reservoir production zones. During the fracturing process, a special fluid (primarily a mixture of sand and water) is blown out at a high pressure into the shale rock formation creating channels through which hydrocarbons can easily migrate to the well. Multi-stage fracturing is a combination of fracturing and plugging processes.…

properties of basic fluid flow we which know today as “Bernoulli’s Principle” (The Doc). Though many are informed on the basis of Bernoulli’s Principle, how many of us can say we are familiar with the math behind this theory? To refresh your memory, Bernoulli’s Principle states that the pressure of a fluid decreases in areas where the flow velocity increases. Imagine…

control volume, operating at steady state. Pump: The liquid condensate leaving the condenser at the state 1 is pumped to the operating pressure of the boiler. The pump operation is considered isentropic. Boiler: The heat is supplied in the working fluid (feed water) in the boiler and thus vapour is generated. The vapour leaving the boiler is wther saturated at the state 3 or superheated at the state 311, depending upon the amount of heat supplied in the boiler. Steam power plant that operates…

Surface and center temperature of the mushroom, ambient humidity and temperature of vacuum chamber have been measured and recorded by the data logger inside the vacuum chamber (see Fig. 1). On the other hand, the control unit that records the pressure data is located outside the vacuum chamber (see Fig. 1). The measured data saved for each 10 seconds. Before starting the cooling, vacuum pump runs half an hour for stabilizing the system. Experiments carried out for three replicates and the…
