Thesis Overview

<p> </p><p><strong>1.0 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</strong><strong>INTRODUCTION</strong></p><p>The study of fluid behaviour is very important in process engineering. It constitutes the study of unit operation. The branch of engineering that deals with the study of fluid is called fluid machines. An understanding of fluids through pipe, pumps and all kind of process equipment and also for the study of heat flow and pressure change. The branches of fluid machines include fluid static and fluid dynamics fluid static treats fluids in the equilibrium state of no shear streets while fluid dynamics deals with position of fluid in motion relative to other part.</p><p>A fluid is a substance that foes not permanently resist distortion. An attempt to change the shape of a mass of fluid result inlayers of fluid scliding over one another until a new shape, shear stress exist, the magnitude of it depend on the viscosity of the fluid and rate of sliding but when final shape is reached, all shear stress will have disappeared.</p><p>The term flow means volume per unit time at specified temperature and pressure conditions.</p><p>It can be measured using positive displacement meter or rate meter. The term fluid is a generalized name given to liquid and gases. Fluid flow or is transported from one place to another by different means either by container gallon, cylinder, tank &nbsp; the related means to the topic at and now is transportation by pipe.</p><p>Pile consist of nozzles and ducts through which liquid flow. A nozzle is a mechanism which kinetic energy of fluid is converted and increased in an adiabatic process.</p><p>T his process accompanies decrease in pressure and change in flow area of the fluid.</p><p>The variation in shape and diameter of different part of nozzle effect the flow of fluid nozzle comes in different types, we have divergent nozzles, convergent nozzles and divergent-convergent nozzles.</p><p>The rate of flow of fluid in pipe is measured by devices which facilitates the ascertainment of the volume of fluid flowing in a unit time. These devices are collective called flow meter or rate meters.</p><p>Flow meters are of different types such as venturi-meter, flow nozzle, orifice meter, rofa meter and weirs these devices are used as choice. All the devices mentioned above facilitates movement of fluid on specified direction, speed and size.</p> <br><p></p>
