Water is flowing through a horizontal pipe of non-uniform cross-section. In the region of narrowest part inside the pipe, the water will have
Options
- Amaximum velocity and minimum pressure.
- Bboth the pressure and velocity maximum.
- Cboth the pressure and velocity minimum.
- Dmaximum pressure and minimum velocity.
Correct answer
A. maximum velocity and minimum pressure.
Step-by-step solution
By equation of continuity A ₁ ~V ₁= A ₂ ~V ₂ Hence if area of cross-section decreases, the velocity increases. By Bernoulli's equation p+ 1 2 V²= constant if V increase pressure decreases. Hence in the narrowest part, velocity is maximum and pressure is minimum.
