In the case of steady flow of a fluid, the acceleration of any fluid particle is A. constant B. variable C. zero D. zero under limiting conditions

The correct answer is C. zero.

In the case of steady flow of a fluid, the acceleration of any fluid particle is zero. This is because the velocity of a fluid particle does not change with time. The velocity of a fluid particle is the rate of change of its position with

respect to time. In the case of steady flow, the velocity of a fluid particle is constant, so the acceleration of the fluid particle is zero.

Option A is incorrect because the acceleration of a fluid particle is not constant in the case of steady flow. The acceleration of a fluid particle is zero.

Option B is incorrect because the acceleration of a fluid particle is not

variable in the case of steady flow. The acceleration of a fluid particle is zero.

Option D is incorrect because the acceleration of a fluid particle is not zero under limiting conditions in the case of steady flow. The acceleration of a fluid particle is always zero in the case of steady flow.
