Pressure in a rotating body of liquid calculator

This online calculator allows you to calculate the pressure of a rotating body of liquid with a given density at a specified radius. Note that gravity is not accounted for and the pressure is relative to the pressure at r=0. See this forum post for more details on the formula.

You can enter values with SI suffixes like 12.2m (equivalent to 0.012) or 14k (14000) or 32u (0.000032).
The results are calculated while you type and shown directly below the calculator, so there is no need to press return or click on a Calculate button. Just make sure that all inputs are green by entering valid values.




\omega = 2\cdot\pi\cdot n[Hz]
P = \frac{1}{2}\cdot\rho\cdot\omega²\cdot r²
