Bernoulli’s Equation in Streamlined Flow

Bernoulli’s equation describes energy in a moving fluid. It comes from the conservation of energy principle, or the work-energy theorem, applied to an incompressible, inviscid fluid in laminar, steady, irrotational flow.

The equation says that pressure energy, potential energy, and kinetic energy...

Assume an incompressible, laminar fluid at a steady state passing through a non-uniform cross-sectional tube.

As the fluid is incompressible, the volume of the fluid element and its mass remain constant.

The speed of the fluid element entering and leaving the tube is different, resulting in net kinetic energy change.

The for...
