[amp_mcq option1=”constant” option2=”variable” option3=”zero” option4=”zero under limiting conditions” correct=”option3″]
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.
