What do you mean by RMS velocity?

The root mean square velocity is the square root of the average of the square of the velocity. As such, it has units of velocity. The reason we use the rms velocity instead of the average is that for a typical gas sample the net velocity is zero since the particles are moving in all directions.

How to Calculate Pressure?

Pressure calculator uses Pressure=(1/3)*Density of Gas*(Root mean square velocity)^2 to calculate the Pressure, Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. ... Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as ​1⁄760 of this. Pressure and is denoted by P symbol.

How to calculate Pressure using this online calculator? To use this online calculator for Pressure, enter Density of Gas (ρ) and Root mean square velocity (Vrms) and hit the calculate button. Here is how the Pressure calculation can be explained with given input values -> 0.042667 = (1/3)*0.00128*(10)^2.

FAQ

What is Pressure?
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. ... Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as ​1⁄760 of this and is represented as P=(1/3)*ρ*(Vrms)^2 or Pressure=(1/3)*Density of Gas*(Root mean square velocity)^2. The density of Gas is defined as mass per unit volume of a gas under specific conditions of temperature and pressure and The Root mean square velocity is the square root of the average of the square of the velocity. As such, it has units of velocity.

Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as ​1⁄760 of this is calculated using Pressure=(1/3)*Density of Gas*(Root mean square velocity)^2. To calculate Pressure, you need Density of Gas (ρ) and Root mean square velocity (Vrms). With our tool, you need to enter the respective value for Density of Gas and Root mean square velocity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Pressure?
In this formula, Pressure uses Density of Gas and Root mean square velocity. We can use 3 other way(s) to calculate the same, which is/are as follows -
  • Pressure=Force/Area
  • Pressure=Density*Acceleration Due To Gravity*Height
  • Pressure=(specific weight of liquid)*(Height)
