Type: MCQ-diagram based-Hard-Class 11

Consider a container open at the top to the atmosphere with an orifice on the side near the bottom. If the speed of efflux of the fluid from the orifice is determined by Torricelli’s law, which of the following expressions correctly represents the speed of efflux v1?

Question diagram
A

v1 = 2gh\sqrt{2gh}

B

v1 = gh\sqrt{gh}

C

v1 = gh2\frac{gh}{2}

D

v1 = 2gh2\sqrt{gh}

Correct Answer

Option A

Detailed Explanation

Torricelli’s law states that the speed of efflux v1 from an orifice at depth h is given by 2gh\sqrt{2gh}, derived using Bernoulli’s equation.
