RMS Velocity

Equation and meaning

\[v = sqrt ( ( ( ( 3 \cdot PV ) ) / ( M ) ) )\]

RMS Velocity Where : v is the Speed of Sound,R is the Gas Constant,T is the Absolute Temprature,M is the Molecular Mass of Gas,

Variables in this formula

M — M
Enter this value unless it is the selected unknown.
PV — Pv
Enter this value unless it is the selected unknown.
v — Velocity
Velocity SI unit: m/s

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
