Why is the velocity of approach idea essential in fluid mechanics?
16. Why is the velocity of approach idea essential in fluid mechanics?
- It influences the fluid's viscosity
- It determines the fluid's temperature
- It impacts the pressure distribution on surfaces
- 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.
