In a streamline flow

A

The speed of a particle always remains same

B

The velocity of a particle always remains same

C

The kinetic energies of all particles arriving at a given point are the same

D

The potential energies of all the particles arriving at a given point are the same

Text Solution

Verified by Experts

The correct Answer is:
C
In streamlined flow, velocity of all the particles arriving at a common point reamains same with time (both in magnitude and direction ). So the KE = `1/2mv^2 = a`
Constant for all the particles as all fluid particles have identical mass also
