Answer to Question #198189 in Physics for Miriama Tamaivena

Question

Explain Bernoulli’s Theorem with the help of a diagram and state the equation as well.

Answer 1

The relationship between pressure and velocity in fluids is described quantitatively by Bernoulli’s equation. Bernoulli’s equation states that for an incompressible, frictionless fluid, the following sum is constant:

$$P+0.5\rho v^2+\rho gh=constant$$

where P is the absolute pressure, ρ is the fluid density, v is the velocity of the fluid, h is the height above some reference point, and g is the acceleration due to gravity.
