Energy of a Flowing Fluid
Category : JEE Main & Advanced
A flowing fluid in motion possesses the following three types of energy
| Pressure Energy | Potential energy | Kinetic energy |
| It is the energy possessed by a liquid by virtue of its pressure. It is the measure of work done in pushing the liquid against pressure without imparting any velocity to it. | It is the energy possessed by liquid by virtue of its height or position above the surface of earth or any reference level taken as zero level. | It is the energy possessed by a liquid by virtue of its motion or velocity. |
| Pressure energy of the liquid PV | Potential energy of the liquid mgh | Kinetic energy of the liquid \[\frac{1}{2}m{{v}^{2}}\] |
| Pressure energy per unit mass of the liquid \[\frac{P}{\rho }\] | Potential energy per unit mass of the liquid gh | Kinetic energy per unit mass of the liquid \[\frac{1}{2}{{v}^{2}}\] |
| Pressure energy per unit volume of the liquid P | Potential energy per unit volume of the liquid \[\rho gh\] | Kinetic energy per unit volume of the liquid \[\frac{1}{2}\rho {{v}^{2}}\] |
