Hydraulic Pipe Diameter Calculator
Calculate the pipe bore size, fluid speed or pump flow in hydraulic system using this calculator.
You should know if you are calculating a 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.
Enter your known values and select units, enter a zero in your unknown value.
|PIPE TYPE||ALLOWABLE SPEED VALUES|
|SUCTION PIPE:||From 0.5 a 1 m/sec|
|RETURN PIPE:||From 1,25 a 3 m/sec|
|PRESSURE PIPE:||3,25 m/sec for Pressure up to 100 Bar|
|PRESSURE PIPE:||From 3,5 to 5 m/sec for Pressure up to 150 Bar|
|PRESSURE PIPE:||From 5,25 to 7 m/sec for Pressure up to 200 Bar|
|PRESSURE PIPE:||From 7,25 to 9 m/sec for Pressure up to 350 Bar|
