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.
