Ratio of pressure and inertia force gives ______________ number?
Correct answer: C. Euler
- A. Weber
- B. Mach
- C. Euler
- D. Froude
Explanation
The Euler number is the ratio of pressure force to inertial force, commonly written as Eu = ΔP/(ρV²) apart from the chosen constant factor. Weber and Froude numbers compare different force effects.
