Q. |
Which among the following force is developed due to resistance of a fluid flow? |
A. | Viscous force |
B. | Inertial force |
C. | Gravity force |
D. | Pressure force |
Answer» A. Viscous force | |
Explanation: Viscous force is the force that is developed due to resistance of a fluid flow. Viscous force is equal to the product of shear stress due to viscosity and surface area of the fluid. It acts in the opposite direction to that of the acceleration. |
