Calculate faster. Design smarter. Verify with confidence.
A modern ProcessFunda experience for chemical and process engineers: searchable calculators, clean inputs, instant results, saved units, mobile-first layouts, and a professional interface built for speed.
Pressure Drop — Liquid
Smart units, validation, and instant output preview.
Calculator library
Search-first layout so users do not have to scroll through long menus. Group calculators by real engineering tasks.
Pressure Drop
Liquid, gas/vapor, two-phase, steam, and pressure/head conversion.
Safety Valve
Liquid, gas, two-phase PSV sizing, rupture disk, AIV and FIV checks.
Pump
Hydraulic power, NPSHa, acceleration head, pump efficiency and related tools.
Storage Tank
Normal vent, emergency vent, PVRV sizing, heating, heat loss and level.
Flare
KO drum sizing, flare stack diameter, height and related checks.
Control Valve
CV calculations for liquid, gas and vapor services.
New UIProperty Estimator
EOS/property package driven density, enthalpy, entropy, viscosity and more.
Physical Properties
Gas density, vapor pressure, API gravity, two-phase density and viscosity.
Heat Loss
Pipe/tank heat loss calculations using practical engineering inputs.
Separator
Vertical two-phase separator sizing and vessel related calculations.
Pipe Utilities
Pipe ID/OD, pipe hold-up volume, restriction orifice and wedge meter sizing.
Cooling Tower
Losses, make-up water and quick cooling tower utility calculations.
What makes it world class
Designed for engineers who need speed, clarity, repeatability, and fewer input mistakes.
Minimal JavaScript, optimized CSS, lazy-loaded calculators, no heavy animation libraries, and cache-friendly assets.
Users can type “PSV gas”, “NPSH”, “API gravity” or “control valve” and reach the exact calculator quickly.
Large fields, sticky calculate buttons, smart unit selectors, error messages near inputs, and field-friendly readability.
Outputs grouped into primary result, assumptions, warnings, unit conversions, and printable calculation summary.
Add PDF/print summary with inputs, formulas, results, date, disclaimer, and revision number.
Prominent verification disclaimer, formula references, assumptions, and “do not use for final design without checking.”
Recommended user journey
The new site should feel like a professional engineering cockpit, not a blog menu. Every page should guide the user from problem → inputs → result → verification.
Choose task
Search or browse by category: hydraulics, safety, equipment, properties, utilities.
Enter data
Use smart unit selectors, default values, field hints, and validation before calculation.
Review results
Show primary output, secondary outputs, warnings, formulas and assumptions.
Export or share
Print, copy results, generate report, or save recent calculations locally.
Built for preliminary engineering checks
All calculators should keep the existing safety position clear: results are educational/reference estimates and must be independently verified before real-world engineering, safety, regulatory, or commercial use.
