Discover Physics with free Physics Revision Notes and Physics Calculator: Bernoulli Principle. This image shows the properties and bernoulli principle formula for the Bernoulli Principle. The Bernoulli Principle Calculator will calculate the flow speed at one end of a horizontal tube and the flow speed at the end of a non-horizontal tube or opening. The Bernoulli Principle Calculator also has a supporting Physics tutorial which eplains the concepts of the Bernoulli Principle.

Bernoulli Principle Calculator Limitations

The second part of the Bernoulli Principle Calculator will only work if the input area is much greater than the output area.

Flow speed at one end of a Horizontal Tube Formula and Calculation

You can calculate the flow speed at one end of a horizontal tube using the following formula, note that when you enter information into the Bernoulli Principle Calculator the calculations will be updated in relation to the Bernoulli Principle formula so you can check the accuracy of your own manual calculations.

v₂ = A₁ × v₁/A₂

Flow speed at the end of a Non-horizontal Tube or Opening Formula and Calculation

You can calculate the flow speed at the end of a non-horizontal tube or opening using the following formula:

v₂ = √2 × (P₁ - P₂ )+ρ∙g∙(h₁ - h₂ ) + ρ × v²₁/2/ρ

Note that when you enter information into the Bernoulli Principle Calculator to calculate the flow speed at the end of a non-horizontal tube or opening the calculations will be updated in relation to the Bernoulli Principle formula so you can check the accuracy of your own manual calculations.
