In a Streamline Flow, - Physics

Short Note

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 the particles arriving at a given point are the same
(d) the momenta of all the particles arriving at a given point are the same

Solution

(c) the kinetic energies of all the particles arriving at a given point are the same
(d) the momenta of all the particles arriving at a given point are the same

In a streamline flow, every fluid particle arriving at a given point has the same velocity v. Thus, the kinetic energies `(1/2"mv"^2)`and momenta (mv) of all particles arriving at a given point are the same, as the mass of a particle is constant. 

  Is there an error in this question or solution?
