Pipe pressure drop calculation is a complicated engineering calculation. Below are the links to Homedepot and Alibaba website for your convenience. If you are looking for a big quantity of pipe material with a good price, Alibaba website may be a good place to look at. You can have a look at Home Depot and other construction material website. To find pipe materials for a small project in USA and Canada. In this situation you may want to use the upper value in above table or use a bigger value than what is shown in above table. Also rust and fouling in a pipe can significantly increase pipe surface roughness. For example concrete surface has different roughness when construct using different method. Since some pipe material has a wide roughness range, you need to select a proper roughness value base on your actual situation. For details click below button to see the video on how to calculate the pipe pressure step by step.īelow are the absolute roughness of some popular pipe material. Then you can find the calculation results in the bottom section almost at the same time. To calculate the pressure drop in a pipe with the calculator, simply fill in the pipe information and fluid information in the top section. It is not accurate for using in multiple phase flow calculation though. The Pressure Gradient given Total Required Power formula is defined as the rate at which pressure varies with radial horizontal distance is calculated using Pressure Gradient - Power /(Length of Pipe Area Mean velocity).To calculate Pressure Gradient given Total Required Power, you need Power (P), Length of Pipe (L), Area (A) & Mean velocity (V). The Colebrook friction factor, sometimes called Moody friction factor, is most popularly used in single phase flow pressure drop calculation. The friction factor is calculated with Colebrook equation through an iterative process so that the result is a true Colebrook friction factor instead of an approximation. This calculator employ the best pressure drop calculation method – Darcy-Weishach equation.

It can be used to calculate any liquid or gas flow pressure drop in pipes with varies type of materials. The pipe pressure drop calculator at the left side was developed by OilGas engineers. PIPE PRESSURE DROP CALCULATION INSTRUCTION
