Process Engineering Calculators
In development — coming soonProcess engineering calculators cover unit operations — the balances, duties, and separation stages behind a plant flowsheet. This category is in development and no tools are published yet.
The planned tools use IAPWS-IF97 for steam and water properties, LMTD with an F-correction for heat exchangers, and the standard shortcut methods for distillation. Relief sizing will follow API 520 rather than a generic orifice equation.
Until then, nothing on this page is a working tool. The lists below show what the category will hold and which published calculators already overlap with it, so a visit here does not end in a dead end.
What This Category Will Cover
Planned tools. None of these are live yet, so they are not links.

Published calculators that already answer part of a process engineering question.
Steam Pipe Sizing Calculator — Velocity & Pressure Drop
Size dry saturated steam pipe by velocity or Darcy-Weisbach pressure drop, with IAPWS-IF97 steam tables and the governing method named. Steel Sch 40 and Sch 80.
Calculate nowFlash Tank Sizing Calculator
Calculate flash tank volume, flash steam flow, condensate flashing rate, and vessel size in Imperial or Metric units. Size a flash tank for condensate pressure drop and steam separation.
Calculate nowHeat Exchanger Calculator
Calculate heat exchanger heat duty using overall heat transfer coefficient, heat transfer area, and log mean temperature difference (LMTD) in imperial or metric units.
Calculate nowSteam Trap Capacity Calculator
Calculate required steam trap condensate capacity in lb/h or kg/h from condensate load, startup factor, and differential pressure. Compare against selected trap capacity with UNDERSIZED / ACCEPTABLE / RECOMMENDED / OVERSIZED sizing categories.
Calculate nowDeaerator Vent Rate Calculator
Calculate deaerator vent rate, vent steam loss, and vent rate as a percent of steam load. Screen deaerator venting for oxygen removal and steam economy in Imperial or Metric units.
