Bernoulli's Equation

For Ideal fluid:

 

The Bernoulli's equation states that, For a perfect incompressible liquid, flowing in a continuous stream, the total energy of a particle remains the same, while the particle moves from one point to another. 

For Real fluid:

The Bernoulli's equation for real fluids is given by

Where,

            h_L = Loss of energy between sections 1 and 2
