In this case, -6 hose would indie a hose with an inside diameter of 6/16”, or 3/8". In another example, a -10 tube would indie a tube with an outside diameter of 10/16", or 5/8". Fittings are a little different and slightly more complex. In the part nuer 10343-8-6, for example, -6 is the hose size and -8 is the size of the fitting end
The Hydraulic Piping Standard Handbook assists in the above mentioned engineering process by providing relevant information and standards for this project input phase. This is when the piping requirements are defined such as desired working pressure, maximum pressure, maximum flow rate, acceptable pressure drops and classifiion requirements.
Water Flow (GPM/GPH) based on Pipe Size and Inside/Outside Diameters : Assume Gravity to Low Pressure. About 6 f/s flow velocity, also suction side of pump: Assume Average Pressure (20-100PSI). About 12 f/s flow velocity: Assume "High Pressure" PEAK flow. About 18 f/s flow velocity : Pipe Size …
If the line crosses the Hose I.D. column between sizes, use the next larger I.D. In the illustration, a 5/8″ hose is recommended for a 10 gpm flow rate at 10 fps velocity. NOTE: Unless flow of hydraulic fluid is intermittent or occasional, recommended velocities should not be exceeded. Download PDF
Pressure ratings are for annealed steel tubing “hydraulic grade” having a tensile strength of 55,000 PSI (the kind most often used for pluing hydraulic systems). See notes on back for adjustment to other steels. Pressure ratings are shown for S.F. (safety factors) from …
Hydraulic Hose Sizing. Flow speeds at the lower end of the ranges should be used when designing for a continuous duty system. The inside diameter of the hoses should be chosen such that the needed flow rates can be supplied at fluid speeds within the acceptable ranges listed above.
Pressure drop values listed are typical of many petroleum based hydraulic oils at approximately +100° F (+38° C). Differences in ﬂuids, ﬂuid temperature and viscosity can increase or decrease actual pressure drop compared to the values listed. Lite r s per mi n ute Hose Pressure Drop* Hose pressure drop in KPa per 10 meters of hose length.

Nuer, or Dash Size, is the measure of a hose’s Inner Diameter (I.D.) in sixteenths of an inch. (The exception to this is SAE 100R5 hose. See the chart below for complete details.) This measuring system of the inside diameter of the hose is universally used by the fluid power industry today. Don’t know the hose size? Check the layline. If the
Computes a flow-rate in GPM given a psi and coefficient of the flow device. Q = 29.84 x √P x D² x C Q = flow-rate in GPM P = velocity pressure in psi D = orifice diameter in inches C = coefficient of flow device. Equation for Determining Rated Capacity. Computes the flow-rate available at a specified residual pressure (a.k.a. Rated Capacity
In selecting hose for hydraulic systems, the consistent with reasonable hose size (see Chart 2): Velocity of pressure lines 7 to 15 ft./sec.Velocity of short pressure lines to 20 ft./sec.Velocity of suction lines 2 to 5 ft./sec. To use Chart 2, lay a lbs./in.2 at a flow rate of 10 gal./min. If the hose in question is 50 feet long, the
Enter your appliion’s fluid properties, hose and coupling specifiions, and our Fluid Flow Pressure Calculator will help identify your operational issues, so you can eliminate costly downtime, improve efficiency, and save money.
To help select pipe size, the chart in Figure 3-1 shows flow (in cfm) down the left-hand side, length of run (in feet) across the top, and minimum Schedule 40 pipe size in the body at the intersection of these two. This chart is based on a 1-psi pressure drop for the run lengths given.
Flow Rate of Fluids in Pipes. The quantity of fluid that will be discharged through a hose depends on the pressure applied at the feed end, the hose length and bore diameter. The surface character of the bore, the nuer, and shape of bends incorporated in the run of the hose also influence the flow rate.
Mar 16, 2017· To find the bore size for a Pressure Line consistent with a Flow Rate of 100 litres per minute (26 US or 22 Imperial gallons per minute), and a Flow Velocity of 4,5 metres per second (14.8 feet per second), connect Flow Rate to Flow Velocity and read Hose Bore on centre scale.
Any restriction of inlet flow will cause the pump to cavitate and ultimately destroy itself. Use a pipe, tubing, or hose chart to determine the proper diameter pipe. Charts are available from the manufacturer. Since a schedule 40 pipe would be required for a suction line, we will use the sample schedule 40 pipe chart in Figure 5 to size the line.
Aug 17, 2017· Simply put, a dash size refers to an I.D. of a hydraulic hose or fitting in 1/16" increments. For example, -6 hose would indie a hose with I.D. of 6/16" - or 3/8". Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter.
Hydraulic Hose Fittings & Connector Sizes Charts Sapphire Hydraulics | February 4, 2020. Hydraulic hose fittings are very useful when it becomes necessary to connect various conductors such as tubes, pipes, and hoses in a hydraulic system.Most of these connections will have a male and component to accommodate the connection and will assist with the process of containing and directing
An illustration will show the principles. See Chart No. 1 Example: A 5/8” inside diameter x 100’ of hose is coupled to a house faucet which maintains a pressure of 40 PSI. Determine flow rate. Solution: Enter Chart No. 1 at 40 psi on the bottom scale. Move vertically to the 5/8” diameter line, and then left to the vertical flow rate scale.
Note that at high flow rates the dynamic pressure at the hose bib often drops because of internal pressure losses in the water delivery system. The assumed C factor (internal to the equation constant) is 135 for flexible garden hoses. Water Flow Rate. Where: = Water flow rate from the end of the hose …

When a hydraulic motor is used instead of a single-end-rod cylinder, the oil flow at all points will be the same as the pump flow. How to Use the Chart Take each section of pluing on your fluid diagram and identify it with one of the lines in the first column of the chart.
Your recommended flow velocity is 20 feet per second. You just need the dash size. You can see where the line drawn against the straight edge passes the dash-size column. In this instance, you need a 5/8" hose, or dash size 12. Need more help? Consider rubber-coated hydraulic hoses with …
The hydraulic radius, R, is the proportion between the area and the perimeter of your pipe. If the pipe is circular, you will find it according to the following equation: R = A / P = πr² / 2πr = r / 2 = d / 4. where r is the pipe radius, and d is the pipe diameter. You can view and modify all these parameters (area, perimeter, hydraulic radius) in the advanced mode of this pipe flow calculator.
