Bernoulli Equation

 

Bernoulli Equation with Head Loss The Bernoulli equation is an approximate relation between preesure, velocity, and elevation, and is valid in regions of steady, incompressible flow where net frictional forces are negligible. Problems related to real fluids can be analysed with the help of a modified form of Bernoulli’s equation as

 

 

 

 

Where P = presure, = density of fluid, g =gravity, z = height of pipe,

v = velocity of fluid, Hf = friction head loss
