In steady flow of a fluid, the total accele ration of any fluid particle A. can be zero B. is never zero C. is always zero D. is independent of coordinates

The correct answer is A. can be zero.

In steady flow, the velocity of a fluid particle at a given point in space does not change with time. However, the velocity of a fluid particle can change as it moves from one point to another. The total acceleration of a fluid particle is the sum of its local acceleration and its convective acceleration. The local acceleration is the rate of change of

the velocity of the fluid particle at a given point in space. The convective acceleration is the rate of change of the velocity of the fluid particle as it moves from one point to another.

The local acceleration of a fluid particle can be zero if

the velocity of the fluid particle is constant at a given point in space. The convective acceleration of a fluid particle can be zero if the velocity of the fluid particle is not changing as it moves from one point to another.

Therefore, the total acceleration of a fluid particle can be zero if the local acceleration and the convective acceleration are both zero.

Option B is incorrect because the total acceleration of a fluid particle can be zero. Option C is incorrect because the total acceleration of a fluid particle can be nonzero. Option D is incorrect because the total acceleration of a fluid particle is not independent of coordinates.
