The complete worked solution.
Every step explained — no skipped algebra.
Bernoulli’s theorem assumes incompressible, non-viscous flow and streamline (laminar) motion. It explains lift in aeroplane wings (due to pressure differences). It does not hold true for turbulent flows where assumptions break down.
