Can Bernoulli's equation be used to describe the flow of water through a rapid in a river? Explain.

Text Solution

Verified by Experts

Bernoulli's theorem is applicable only for there it ideal fluids in stremlined motion. Since the flow of water in a river is rapid, way cannot be treated as streamlined motion, the theorem cannot be used.

Statement-1 : Bernoullis equation is based on energy conservation. Statement-2 : Bernoullis equation can only be applied if the flow is streamlined. Statement-3 : Bernoullies equation can be applied evern if the flow is not streamlined as total energy is always conserved.

Assertion: Bernoulli's equation hold for non-steady or turbulent flows. Reason: In these situations, velocity and pressure are constant with time.
