Water is flowing through a horizontal pipe in stream line flow. At the narrowest part of the pipe (a) velocity is maximum and pressure minimum. (b) pressure is maximum and velocity minimum. (c) both pressure and velocity are minimum. (d) both pressure and velocity are maximum.

Answer: (a). Continuity: Av = constant, so the speed is largest where A is smallest. Bernoulli (horizontal): P + 1/2ρ v² = constant, so larger v means smaller P. So the answer is (a) velocity maximum, pressure minimum.

Bernoulli's Equation

Water is flowing through a horizontal pipe in stream line flow. At the narrowest part of the pipe

Show answer and solution

Answer: (a)

Continuity: $Av$ = constant, so the speed is largest where $A$ is smallest.
Bernoulli (horizontal): $P + \frac{1}{2}\rho v^2$ = constant, so larger $v$ means smaller $P$ .
So the answer is (a) velocity maximum, pressure minimum.
