Question

The type of flow, if \(\dfrac{\partial v}{\partial s}=0\), is

• A. Uniform flow
• B. Non-uniform flow
• C. Steady flow
• D. Unsteady flow

Hint:

Flow classifications: \[ \boxed{ \begin{aligned} \frac{\partial v}{\partial s}=0 &\Rightarrow \text{Uniform Flow}\\[2mm] \frac{\partial v}{\partial t}=0 &\Rightarrow \text{Steady Flow} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Interpret the given condition. The symbol \(s\) represents the distance along the flow direction. \[ \frac{\partial v}{\partial s}=0 \] means that the velocity does not change with position.

Step 2: Identify the flow type. Since velocity is constant along the flow path, \[ \boxed{\text{Uniform Flow}} \] is obtained. Hence, \[ \boxed{(A)} \] is the correct answer.
