Consider the following statements:
1. A streamline is an imaginary line within the flow for which the normal at any point.
2. Convective acceleration is the change in velocity with respect to distance only.
3. Temporal acceleration expresses variation of velocity with respect to time only.
4. Both convective acceleration and temporal acceleration and temporal acceleration can coexist.

Solution

The correct option is D 2, 3 and 4 only
(d)
A streamline is an imaginary curve drawn through a flowing fluid in such a way that the tangent to it at any point gives the direction of the velocity of flow at that point.
