Energy of a Flowing Fluid
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 |
Pressure energy per unit mass of the liquid |
Potential energy per unit mass of the liquid gh |
Kinetic energy per unit mass of the liquid |
Pressure energy per unit volume of the liquid P |
Potential energy per unit volume of the liquid pgh |
Kinetic energy per unit volume of the liquid |
