BERNOULLI EQUATION

bernoulli-equation

Bernoulli Equation is a statement of the conservation of energy principle appropriate for dynamic fluids. The behavior of  “Bernoulli effect” is the lowering of fluid pressure in regions where the flow velocity is increased.  At high velocity flow through the constriction, kinetic energy must increase at the expense of pressure energy.

 
Bernoulli equation v2/2   +  p/r +  gh = cst.

                                            

  

Dynamic pressure pd = rv2 / 2
Energy conservation on streamline rv12 /2  + p1 = rv22 /2  + p2

v = flow speed

p = pressure 

r= density

g=gravity    

h = height
