series and parallel 2. To show shut off point of pump in series and parallel ABSTRACT / INTRODUCTION Pump is a general term for any fluid machine; used to transfer and add energy to fluid in a system‚ either at the same level or to a new height. There are some fundamental parameters used to determine the performance of a pump. The mass flow rate of fluid is the obvious primary pump performance parameter and for incompressible flow‚ it is more common to use volume flow rate rather than mass

SEDIMENTATION According to Brown (1950)‚ sedimentation is the separation of a suspension into a supernatant clear fluid and a rather dense slurry containing a higher concentration of solid. According to Perry ()‚ sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening‚ whose purpose is to increase the concentration of suspended solids in a feed stream; and clarification

ABSTRACT Metal cutting fluids changes the performance of machining operations because of their lubrication‚ cooling‚ and chip flushing functions. Typically‚ in the machining of hardened steel materials‚ no cutting fluid is applied in the interest of low cutting forces and low environmental impacts. Minimum quantity lubrication (MQL) presents itself as a viable alternative for hard machining with respect to tool wear‚ heat dissertation‚ and machined surface quality. This study compares the mechanical

Conclusion 80 References 81 Appendix I.A Appendix II.A Appendix II.B Summary There are two parts in this experiment where we shall observe the mechanics of fluid flow in a closed conduit and also to find out the characteristics of a centrifugal pump. In the first part‚ we applied the principle of pressure difference across fittings in a closed conduit to find out the loss coefficients of these fittings.

Manufacturing of Aerogel Aerogel was found by Steven Kistler in 1931‚ but its application cannot be in the market and consumer because there is no item that can use the aerogel. The 1980s the aerogel have a place to be a raw material in existing and new product after they discover a new research about aerogel. They have been considered as a new development material that better than polyurethane foam in refrigerators‚ and as a heat insulator for windows. Aerogel is produced by removing all the

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

convection of a fluid (air) past a copper tube‚ which is used as a heat transfer model. Introduction The general definition for convection may be summarized to this definition "energy transfer between the surface and fluid due to temperature difference" and this energy transfer by either forced (external‚ internal flow) or natural convection. Heat transfer by forced convection generally makes use of a fan‚ blower‚ or pump to provide high velocity fluid (gas or liquid). The high-velocity fluid results
