The Bernoulli's equation describes the relationship between pressure, velocity, and elevation in fluid flow. It states that in an ideal, incompressible fluid flow, the total mechanical energy per unit mass (which includes pressure energy, kinetic energy, and potential energy) remains constant along a streamline.
In simpler terms, Bernoulli's equation states that as fluid flows through a pipe or channel, the total energy of the fluid (pressure energy + kinetic energy + gravitational potential energy) remains constant as long as there are no external forces acting on the fluid. Therefore, if the velocity of the fluid increases, the pressure decreases, and vice versa.
The equation can be expressed as:
P + (1/2)ρv^2 + ρgh = constant
Where:
P represents the pressure of the fluid,
ρ represents the density of the fluid,
v represents the velocity of the fluid,
g represents the acceleration due to gravity,
h represents the height of the fluid above a reference point.
Bernoulli's equation is widely used in fluid dynamics and has various applications, including in the field of aerodynamics, hydraulics, and the design of pipes, nozzles, and wings. It helps in understanding and predicting fluid behavior in different situations.
