numerically describes the flow. The results can be best understood by expressing the flow characteristic in terms of non-dimensionless numbers which measure the ratio of the magnitude of force associated with inertia to the forces arising from fluid viscosity which gives rise to the Reynolds number. If one were to increase a fluid’s inertia - increased mass and acceleration – relative to solid surface and holding other factors constant then Reynolds number would increase (Achela‚ F‚ 2013‚ Lecture Notes)

Characteristics of a Good Hydraulic Fluid Viscosity Viscosity is a measure of a hydraulic fluid’s resistance to flow. It is a hydraulic fluid’s most important characteristic and has a significant impact on the operation of the system. When a hydraulic oil is too thin (low viscosity)‚ it does not seal sufficiently. This leads to leakage and wear of parts. When a hydraulic oil is too thick (high viscosity)‚ the fluid will be more difficult to pump through the system and may reduce operating

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

ABSTRACT Firstly‚ the objectives of the experiment are to observe the characteristics of the flow and to compute the Reynold’s number. Using the Solteq Osbourne Reynold’s Demonstration (model FM 11) in this experiment‚ with different of water volume flowrate‚ the characteristics of the flow could be determined. The rock inside the stilling tank are to calm the inflow water so that there will not be any turbulence interfere with the experiment. The water inlet and outlet valve and dye injector utilized
