Bernoulli's equation stated earlier was based on the assumption that fluid is ideal (i.e., non-viscous) and therefore frictionless.

ENERGY EQUATION

Bernoulli's equation stated earlier was based on the assumption that fluid is ideal (i.e., non-viscous) and therefore frictionless. But practically all fluids are real (i.e., viscous) and therefore there are always some losses during the fluid flow. These energy losses have to be taken into consideration in the application of Bernoulli's equation which gets modified for real fluids as follows:


The equation (3.22) is known as energy equation. This is also called as the modified Bernoulli's equation.

Note 

The knowledge of continuity equation, Bernoulli's equation, and energy equation are very important to keep all energy losses in a fluid power system to a minimum acceptable level. It aids in the proper selection of the sizes of the pipes and fittings that make up the system. The knowledge is also required to perform a complete analysis of a fluid power system.
