# Write an expression indicating the Bernoulli equation, define all the symbols used and state all the conservation of energy involved?

##### 1 Answer

Bernoulli equaton describes the relationship between Pressure and Velocity in a fluid:

#### Explanation:

You can write it as:

where:

Every term has a meaning in terms of energetic properties of the fluid (always considering a volume of your fluid); so:

Bernoulli tells us that an element of fluid "trades" speed for height or pressure during its movement along the tube but its energy remains fixed (conserved) so that if you increase one term the others change accordingly to compensate and maintain the sum constant!!!

hope it helps!
