Bernoulli's principle

Question 1

What does Bernoulli’s Principle state

Answer 1

• Bernoulli’s principle states that as the speed of a fluid increases, its pressure decreases.
• It’s formula can be derived from principle of conservation of energy

Question 2

Bernoulli’s principle formula

Answer 2

P + 0.5 X p X v^2 + p X g X h = constant

P -> Pressure exerted by fluid
v -> Velocity of Fluid
p -> Density of fluid
h -> height of container

Question 3

What does Torricelli’s Law state

Answer 3

It states that the speed of liquid flowing out of a tank depends on the square root of the height
h between the liquid surface and the opening.
