Class 11PhysicsFluid Mechanics and Surface TensionBernoulli's Theorem and Applications of Bernoulli's Theory
EasyWhy is Bernoulli's equation not applicable to turbulent flow? Explain.
(N/A) Bernoulli's equation is based on the assumption of steady,streamline flow where the velocity and pressure at any point remain constant over time. In turbulent flow,the velocity $(v)$ and pressure $(P)$ at any given point fluctuate randomly and change continuously with time. Therefore,the conditions required for the derivation of Bernoulli's equation are not satisfied in turbulent flow.

$A$ horizontal pipe of non-uniform cross-section allows water to flow through it with a velocity $1 \ m/s$ when the pressure is $50 \ kPa$ at a point. If the velocity of flow has to be $2 \ m/s$ at some other point, the pressure at that point should be: (in $kPa$)
