The Euler's number is the ratio of the inertia force to the

Show Hint

Important dimensionless numbers: \[ \begin{aligned} Re&=\frac{\text{Inertia Force}}{\text{Viscous Force}} Fr&=\frac{\text{Inertia Force}}{\text{Gravity Force}} We&=\frac{\text{Inertia Force}}{\text{Surface Tension Force}} Eu&=\frac{\text{Inertia Force}}{\text{Pressure Force}} \end{aligned} \]
