Hydraulic hose is more complied than it seems. There are many factors that go into designing, manufacturing, and testing high-quality hydraulic hoses. At Parker Hannifin Hose Products Division, we take pride in our knowledge of the small details that go into hydraulic hose.

Table 1 is based on the following recommended flow velocities: Pressure lines – 25 ft/sec or 7.62 meters/sec. Return lines – 10 ft/sec or 3.05 meters/sec. Suction lines – 4 ft/sec or 1.22 meters/sec. If flow velocities differ from these, calculate the required flow

How to determine fluid velocity & hose ID Flow velocity is determined by hose bore size and fluid rate. Our engineer has drawn a simple and easy-to-use nomograph to help you determine the media velocity. In most cases, fluid velocity should be among a safe range
The following chart shows oil velocity in relation to Gallons Per Minute within a hose. Recommendation for oils having a maximum viscosity of 315 S.S.U at 100 degrees F, operating at temperatures between 65 and 155 degrees F.
GPM = Gallon per minute fluid flow A = Square inch inside area of conductor The Following velocity charts are a quick way to check velocity through a line. Included in the charts is the I.D. of the line. If the particular tube, pipe or hose you are using is not listed
For industrial hose asselies, there is also a way to fabrie an electrically conductive industrial hose assely by connecting the hose’s metal reinforcement to the hose ends. Note on Galvanic Corrosion: Another consideration should be given to using different materials for tube and tube fittings, or connecting tube or hose fittings to ports made of different materials.

Cylinder Flow Rate (gpm) = 12 x 60 x cylinder speed (ft/sec) x area (in²) / 231 Cylinder Volume Capacity (gals) = cylinder area (in²) x cylinder stroke (ins) / 231 Basic Hydraulic Motor Calculations :
Hydraulic steel tubing also maintains the same outside diameter regardless of wall thickness. Hose sizes indie the inside diameter of the pluing. A 1/2" diameter hose has an internal diameter of 0.50 inches, regardless of the hose pressure rating.
Gates has a calculator on their website that allows you to spell out parameters including flow rate, hose diameter and length, fluid properties and then the nuer of fittings and adapters. It lets you choose between elbows, adaptors and tees, or even straight couplings.

Calculate appliion rate of irrigation drip lines based on the flow rate from individual emitters, the spacing of the emitters, and the spacing between the drip lines. Use this form to calculate the water appliion rate of drip irrigation lines (tape, tubing) given the flow rate from individual emitters, the spacing of the emitters along the drip line, and the spacing between the drip lines.

Most hydraulic hose are rated for -40 F to +212 F temperatures. This is the internal oil temperature, not aient temperature. HOW TO SELECT HOSE DIAMETER See Flow Rate Chart on next page Given the flow rate in gallons per minute (gpm), or cubic
Formula: 0.3208 x GPM ÷ Internal Area = feet per second Note: The outside diameter of pipe remains the same regardless of the thickness of the pipe. A heavy duty pipe has a thicker wall than a standard duty pipe, so the internal diameter of the heavy duty pipe
