The ratio of inertial forces to gravity forces is called the ______________ number?
Correct answer: B. Froude
- A. Mach
- B. Froude
- C. Euler
- D. Weber
Explanation
The Froude number compares inertial force with gravitational force, commonly written as Fr = v divided by the square root of gL. Mach compares inertial and elastic effects, while Weber compares inertial and surface-tension effects.
