Bernoulli’s equation holds only for _______.

CONCEPT:

• Bernoulli's principle states that the sum of pressure energy, kinetic energy, and potential energy per unit volume of an incompressible, non- viscous fluid in a streamlined irrotational flow remains constant along a streamline.
• This means that in steady flow the sum of all forms of mechanical energy in a fluid along a streamline is the same at all points on that streamline.

EXPLANATION:

• From the above definition, it is clear that Bernoulli’s equation holds only for low viscosity and incompressible fluids in streamline flow. Therefore option 4 is correct.
