Shortcuts to Bernoulli Equation

Here are some shortcuts to bernoulli equation. Finding the speed of fluid in a venturimeter and a hole of a fluid tank.

The speed of water out of the hole V and the horizontal range of water trajectory we could find easily with with formulae:

Bernoulli's Equation FAQ

Teacher : What is bernoulli's equation about?
Student : Gases sir!
Teacher : just only gases?
Student : Ehmm,.. water, oil, fluids?
Teacher : Could you write down the bernoulli equation?
Student : Here it is sir,
               P + 1/2 ρ v2 + ρ g h = constant
Teacher : Could you give more explanation what is constant meant in your equation?
Student : That is meant
               P₁+ 1/2 ρ v₁² + ρ g h₁ =  P₂ + 1/2 ρ v₂² + ρ g h₂
Teacher : Consider that you have a horizontal pipe that water flows in it, what will you do with your equation?
Student : We should cancel the h sir, because h₁ = h₂ so the equation will be like this
               P₁+ 1/2 ρ v₁²  =  P₂ + 1/2 ρ v₂²

Teacher : Ok the last state your symbols in the equation and you may go home!
Student : P = pressure in pascal
ρ = fluid density
v = the speed of fluid flows
h = the level of height of a point in the fluid
g = the acceleration due to gravity

Learning Bernoulli Equation from HyperPhysics

Started with Bernoulli equation that contents the equation and the relationships between A, P and v (area, pressure and velocity)

Bernoulli Calculation
Try the calculation of the "real world" pressure, just simple like calculators, enter the number and you'll get the results

Bernoulli applications
you'll find also curve of a baseball, how it interacts with the air and bernoulli principle applied here.
