Enter the flow of oil and the diameter of the pipe into the calculator to determine the oil velocity.

Oil Velocity Formula

The following equation is used to calculate the Oil Velocity.

OV = OF / 60 / (pi*D^2/4)
  • Where OV is the oil velocity (ft/s)
  • OF is the oil flow rate (ft^3/min)
  • D is the diameter of the oil pipe (ft)

To calculate the oil velocity, divide the oil flow rate by 60, then again by the cross-sectional area of the pipe.

What is Oil Velocity?


Oil velocity measures the linear rate of movement through an oil pipeline.

How to Calculate Oil Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Oil Velocity.

First, determine the oil flow rate. In this example, the oil flow rate is found to be 600 ft^3/min.

Next, determine the diameter of the oil pipe. In this case, the diameter of the oil pipe is measured to be 2.5 ft.

Finally, calculate the Oil Velocity using the formula above:

OV = OF / 60 / (pi*D^2/4)

OV = 600 / 60 / (3.14159*2.5^2/4)

OV = 2.037 ft/s
