The Kinetic energy per unit volume appears in total energy equation of a flowing fluid, that does not appear in the total energy equation for a non-flowing fluid.
Kinetic Energy per unit volume is defined as the Kinetic energy of the flowing fluid per unit volume.
Bernoulli Equation is a equation that remains constant for a given fluid which comprises of Potential energy per volume, Kinetic energy per volume and Pressure.
It is given by:
P + ρgh + ρv²/2 = constant
where, P is the Pressure
ρ is the density of fluid
g is acceleration due to gravity
h is the height
v is the velocity
∴ ρgh is called as Potential energy per volume
∴ ρv²/2 is called as Kinetic energy per volume
In a Flowing Fluid:
- P is present
- Potential energy per volume is present
- Kinetic energy per volume is present since velocity is present
In a Non-Flowing Fluid:
- P is present
- Potential energy per volume is present
- Kinetic energy per volume is absent since velocity is absent
Hence, Kinetic Energy per unit volume does not appear in the total energy equation for a non-flowing fluid but appears in total energy equation for a flowing fluid.
