False
Explanation:
Uniform flow is defined as the type of flow in which the velocity is constant, not the acceleration. In uniform flow, the velocity of the fluid particles remains constant at any given point in the flow field over time. This means that the fluid particles travel in a straight line with a constant speed and direction.
However, it does not imply that the acceleration is zero. Acceleration is the rate of change of velocity with respect to time. In uniform flow, the velocity remains constant, but it does not mean that there is no change in velocity over time.
In uniform flow, the fluid particles may change their velocity when they encounter obstacles or boundary conditions, resulting in a non-zero acceleration. For example, if a fluid particle encounters a sudden change in the channel geometry or encounters a boundary, it may experience a change in velocity and hence acceleration.
Therefore, the correct statement is that in uniform flow, the velocity is constant, but the acceleration may or may not be zero depending on the flow conditions.
