Pipe Sizing for Single Phase Incompressible Flow

Important Notices:
 
bulletThe pipe sizing procedure presented here applies to Newtonian fluids which are incompressible and single phase in isothermal and steady-state flow situations. The friction factor is calculated rigorously from the original Colebrook equation. Piping pressure drop and rating are treated elsewhere.
bulletA more comprehensive and powerful version of this procedure is available online through Process Associate's clients gateway (password required). WWW-based and Stand-alone versions of the full program for Windows 3.1x/95/NT and Unix operating systems are available through their coordination office. The full version of this procedure is part of their Process Designer® line of intelligent software.
bulletFor your convenience, The input form below has several multiple choice fields {using radio buttons} with one field already selected as default. Please make sure that you always mark the proper button corresponding to your input if it is different from the default.

Notes:

  1. A Process Associates proprietary correlation reflecting typical "old" piping roughness is used. The correlation is derived from refinery data for steel piping in "clean" gas and liquid services.
