SCFM (Standard CFM) vs. Let’s take a quick look at how to use this chart. To understand the relationship between the pressure drop across a pipeline and the flow rate through that pipeline, we need to go back to one of the most important fundamental laws that governs the flow of fluid in a pipe: the Conservation of Energy, which for incompressible liquids, can be expressed using the Bernoulli Equation. Further evaluation of this chart shows that for the conditions given, the pipe will flow over 800 SCFM at 60 PSIG inlet and 3 PSI (5%) pressure drop. The first. The "HVAC Pipe Sizer - Steam" module allows you to size a steam pipe run, and it also includes a bonus steam table calculator. Where: dL = diameter of the unknown orifice. 5 psi or Less and a Pressure Drop of 3.
