<onlyinclude>'''Pneumatic hydraulic energy''' is the [[energy]] stored in the form of pressurized [[fluid]], making it an application of [[Fluid mechanics|fluid power]].</onlyinclude> Fluid [[power]] is the use of pressurized fluids to generate, control, and transfer power. Fluid power can be divided into two parts: hydraulics, which stores energy in the [[gravitational potential energy]] of a [[liquid]], typically water, and pneumatics, which stores energy in the compression and pressurization of a [[gas]].<ref>A. Akers et. al. ''Hydraulic Power System Analysis.'' New York: Taylor & Francis, 2006</ref>

==Background==
The energy stored in a compressed gas is equivalent to the [[work]] done to compress the gas. This work is given by the equation:

<m>W=P_s V \ln \left( \frac{P_a}{P_s}\right)</m> where;

• <m>W</m> is the [[work]] done to compress the fluid ([[joules]], J)

• <m> V </m> is the volume of the container the fluid is in (cubic meters, m<sup>3</sup>)

• <m>P_s</m> is the [[pressure]] of the compressed fluid ([[pascal]]s, Pa)

• <m>P_a</m> is the pressure of the atmosphere (pascals, Pa)

• <m> \ln() </m> is the natural logarithm

The work done to compress the gas is negative and so the energy stored in the gas is the work done multiplied by -1.

==Application==
Pneumatic hydraulic systems are widely used in industry. It is an efficient and reliable method of energy storage and easy to transport. Pneumatics also has applications in dentistry, construction, vacuum, and [[braking]] systems.
