Disclamier: The calculations in this program are, to the best of our knowledge, current and represent calculations normally used to size high-density polyethylene pipe. ISCO Industries, LLC does not accept responsibility for the use and/or application of these programs. Each project or applicatin has its own set of conditions and input variables. The intrepretation and use of these input variables is important. The user must apply engineering judgement when selecting values for input into these programs. Note: This calculator generates information on the friction head loss of various piping, sizes, and flow rates used in water distribution systems. It offers several standard commercial sizes of pipes, although all combinations of pipe material, SDR's may NOT be valid! Please review ISCO literature for stock sizes. New sizes are being made as demand requires. Please call for current availability of speciality sizes. Call 1.800.345.4726 and ask for Inside Sales. ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ Basis of Calculations: ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ The values calculated are based on NOMINAL pipe dimensions and the Williams/Hazen formula, and published by the Plastic Pipe Institute TR14 March 1971. The WALL thickness is calculated as the minimum WALL plus 4%, rounded to the nearest 0.001 inch. ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ Water Velocity: ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ In general, flow velocity *LESS* than 5 feet per second, is considered to be *SAFE*. Higher velocities may be used in cases where the operating characteristics of valves and pumps are known so that sudden changes in flow velocity can be controlled. ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ The intent of this calculator is to assist in informing users, engineers and others. Interpretation, use, and application is a function and responsibility of the user.
