although the fluid flow is unsteady it has zero acceleration is this possible ? Explain
Homework Answers
Unsteady flow is defined as the flow in which one or more properties are changing with respect to time. The property may or may not be velocity.
For example in a unsteady flow process pressure is continuously changing with respect time , without changing the fluid velocity. In this case the acceleration is zero and flow is unsteady.

Given the velocity field V =107 +(x + y2)7-2xyk [m/s] Is the flow steady or unsteady? Is this motion kinematically possible for an incompressible fluid? Do you think that velocity field can represent a potential flow at specific positions of (x, y)? What is the acceleration of a particle at position (x, y, z) = (3, 1, 0) m?

is it possible for an object to have zero velocity but non-zero acceleration? If so, give an example from your experiments. In any case, explain why. A motion diagram might help.
