Introduction to Hydraulic Machines

All machines, including those with hydraulic or pneumatic systems, require a source of power to work. One of the ways of transmitting this power to the point of operation i.e. the point at which the machine will do its work is by ‘fluid power’.

Fluid power is the method of using pressurized fluid to transmit energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More from one point on the machine to another point. This fluid may be liquid or gas.
