Topic: Fluid Mechanics
Euler's dimensionless number relates the following
- A. inertial force and gravity
- B. viscous force and inertial force
- C. pressure force and inertial force
- D. viscous force and pressure force
Answer: C. pressure force and inertial force
Explanation: Euler Number (Eu) is defined as the ratio of Inertial Force to Pressure Force, i.e., $\sqrt{Fi / Fp}$.
