Wooden or Masonry Pipe Highlighted and italicized friction loss values indicate flow rates that are between 6 feet and 8 feet per second. Embed. Aluminium %PDF-1.5 hL = 10.67 * 100 * 0.041.852 / 1451.852 / 0.254.87, hL = 1067 * 0.0025764 / 10065.921522 / 0.0011694, A collection of really good online calculators.
Frictional head loss and pressure drop can be calculated for given pipe flow rate, pipe diameter and length, pipe roughness, and fluid density and viscosity. 50% 50% found this document useful, Mark this document as useful. Water's viscosity fluctuates in different temperatures, so errors may be present if the temperature is not 60°F (16°C). If the equation is employed at temperatures outside this range, a significant level of error will occur. Pipe Diameter (Inch) Flow (GPM) Head Loss / 100 Feet Pipe Due to Friction (C = 150) Friction Loss Table C = 150 for High Density Polyethylene Pipe (HDPE) Page 2 . cubic foot/minute Cast Iron (30 years old) Calculations Pipe Flow Software. Cement Lining The Hazen-Williams Coefficient (C) fluctuates between around 60 and 160. Cast Iron, Asphalt Coated Friction loss … Click the "Calculate" button and you will be given a result for the pipe's friction loss. !�2�c3v�w����. 3 0 obj The friction head loss (feet H 2 O per 100 feet pipe) in straight plastic pipes made of PVC, PP, PE, PEH or similar - can be estimated from the table below. Acrylonite Butadiene Styrene endobj cm gallon/day Cast Iron (10 years old) Cast Iron (40 years old) Plastic Pipes - Friction Head Loss - Friction head loss (ft/100 ft) in plastic pipes - PVC, PP, PE, PEH; SDR - Standard Dimension Ratio and S - Pipe Series - It is common to use the Standard Dimension Ratio - SDR - as method of rating pressure piping liter/second The K values given below are for making estimates of friction loss in cases not covered in the previous tables.
Asbestos Cement 3. <> ft <> 3. Also the required pipe diameter to carry a given flowrate with a maximum allowable head loss can be calculated.
The equation presupposes a fluid that has a kinematic viscosity of 1.13 centistokes; basically, water. 9 FRICTION LOSS ALONG A PIPE FIT Staffweb. liter/minute
The coefficient will vary over a pipe's lifetime; as such, informed engineering judgements must be made when choosing appropriate values for the analysis of any given pipe system. m
