Hydraulics is the study of fluids at rest or in motion, especially regarding engineering applications. Hydraulic systems use pressurized fluids to gain mechanical advantage and perform work. Basic hydraulic systems include a hydraulic pump to pressurize fluid, a hydraulic motor or cylinder to use the pressurized fluid to do work, and piping to transfer fluid between components. Hydraulic systems provide convenient power transfer with few moving parts and flexibility to distribute force in multiple directions for many uses.
THIS POWER POINT PRESENTATION IS ABOUT DESIGNING AND USE OF HYDRAULIC SYSTEMS.THIS PRESENTATION IS NOT COVERING WHOLE DESIGNING PART BUT YOU CAN REFER IT BY USING LINK GIVEN IN SLIDE NUMBER 12.I AM GRATEFUL TO OTHER AUTHORS WHOSE PRESENTATIONS HAVE WORKED AS REFERENCE FOR THIS PRESENTATION.
COMMENTS ARE ALWAYS WELCOMED.PLEASE FEEL FREE TO GIVE SUGGESTIONS IT HELPS ME TO IMPROVE MYSELF.THANK YOU
Hydraulics today has become a way of life as most applications have some form of system ingrained. This paper is an endevor to present the very basics of hydraulics and overcome its basic fear.
Hydraulic System :- A hydraulic system is a system that uses pressurized hydraulic fluid to power hydraulic machinery.
Pneumatic System :- In Pneumatic system Compressed air is Used instead of Liquid

Different types of flows and lines in fluid flow.Muhammad Bilal
this presentation includes all the possible flows which a fluid can have when it is moving in a 3D space it also contain the different kinds of lines such as stream lines,path lines and streak lines for a fluid flow ( steady and unsteady).
• Hydroelectric power (often called hydropower) is considered a renewable energy source. A renewable energy source is one that is not depleted (used up) in the production of energy. Through hydropower, the energy in falling water is converted into electricity without “using up” the water. Hydroelectric power (hydropower) systems convert the kinetic energy in flowing water into electric energy.
the presentation includes basic ideas about water pumps, various terminology generally used for the pumps, classification of pumps and ideas about the types its construction and working
