Vedclass · Answer

(C) In a streamline flow,the velocity of a fluid particle at any given point is constant over time. This means that every particle that passes through a specific point $P$ will have the same velocity (both magnitude and direction) as the previous particle that passed through that same point $P$. Since kinetic energy $K = \frac{1}{2}mv^2$ depends on the speed $v$ of the particle,and all particles passing through point $P$ have the same velocity,they must also have the same kinetic energy. Therefore,option $C$ is the correct statement.
