In this article, you’ll learn what is the Difference Between Hydraulics and Pneumatic system. And also you can download the PDF file of this article at the end of it.

Difference Between Hydraulics and Pneumatic:

First, let’s start with hydraulics and pneumatic definitions.

Fluid mechanics is that branch of science that deals with the behavior of the fluids at rest as well as in motion. Pneumatics is a branch of engineering that makes use of gas or pressurized air.

Both hydraulics and pneumatics are the application of fluid power. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids.

What is Hydraulics?
Fluid can define as a substance that is capable of flowing and does not maintain its shape for a long time. Fluids have the ability to take the shape of the container depending on the surroundings and flow in a large area when the surroundings is removed.

In physics, a fluid is a substance that continually deforms under applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas, and to some extent, plastic solids. Fluid such as water is used for the conversion of hydraulic energy into mechanical energy to do some useful work.

In the heating, ventilation, and air-conditioning industry (HVAC), liquid such as water is used for the transmission of heat from one area to another. The fluid is a primary element of a hydraulic system, which obeys Pascal’s law to give fluid power.

Examples of Hydraulics systems: Jaws of Life, dump truck lifts, water guns, forklifts, cranes, etc.
