Oil Pipe Diameter Calculator

Oil Pipe Diameter

A guide to the appropriate sizing of Hydraulic pipes can be carried out here. It should be noted that the purpose of the pipe must be known, is it Suction Pipe, Return Pipe or Pressure Pipe? A guide to “normal” fluid speeds within these types of pipes are shown below. Calculated values for Fluid Speed v (m/s) should fall within these ranges.

To calculate Fluid Speed v(m/sec), you must enter the following figures:-

1. Diameter d(mm), this is internal pipe diameter.
2. Pump Flow Q(lpm)

Then press v to calculate, this will be shown in the result box.
