Question

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 eneergies of all the particles arriving at a given point are the same

Answer 1

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