Why is the velocity of approach idea essential in fluid mechanics?

16. Why is the velocity of approach idea essential in fluid mechanics?

1. It influences the fluid's viscosity
2. It determines the fluid's temperature
3. It impacts the pressure distribution on surfaces
4. It affects the density of the fluid

Answer: C) It impacts the pressure distribution on surfaces

Explanation:

When a fluid flows over an obstruction, the velocity of the approach changes the pressure distribution on the surface. It plays a role in designing structures that can withstand fluid forces.
