Velocity of Efflux using Torricelli’s Theorem Calculator

Velocity of Efflux Calculator

Calculate the velocity of efflux using Torricelli’s theorem:
\[ v = \sqrt{2gh} \] where \( g \) is the gravitational acceleration and \( h \) is the height of the fluid column.

* Enter all values in SI units.

Step 1: Enter Parameters

Example: 2 m

Example: 9.81 m/s²

Formula: \( v = \sqrt{2gh} \)


Practical Example:
For a fluid height of 2 m and \( g = 9.81 \) m/s², the efflux velocity is:
\[ v = \sqrt{2 \times 9.81 \times 2} \approx \sqrt{39.24} \approx 6.26\, \text{m/s} \]
