Industrial Gas Tools, With the Equations Left Visible

Field notes

The current offering is a Flow & Control Valves calculator with two operating modes: Required Cv and Available flow. It also performs a choked-flow check and says the result is accompanied by equations, assumptions, units, and limitations. The publisher frames the tools as preliminary decision support rather than a substitute for manufacturer or code verification. The page lists future expansion into piping, pressure relief, thermal, hydrogen, and cryogenic systems, but only one tool is visible now.
