Fluid Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

Fluid velocity is how fast the process is traveling in a pipe.  To calculate the velocity of the fluid, use one of the equations below.

To get flow rate in Feet per Second

Step 1 - Convert the flow rate to cubic feet per second.  This is done by multiplying the flow rate by one of the values shown on the Cubic Feet per Second page.

Next, divide by the flow area.  The information for flow area can be found on the Carbon Steel Pipe Properties page.  Make sure that the units match and convert the area into square feet. 

FORMULA

\(v = \frac { Q } { A  }  \)

Where:

\(v\) = velocity

\(Q\) = volumetric flow rate

\(A\) = area
