Engineering Calculators
Practical tools for sizing, correcting, and verifying liquid and gas flow meter installations. All calculations use industry-standard formulas.
Gas Correction Factor
Correct meter readings for non-standard operating pressure, temperature, and gas type
Calibration: 50 psig
Calibration: 70°F
Calibration: 50 psig · 70°F · Air (SG 1.0)
CF = √( (Pcal/Pact) × (Tact/Tcal) × (SGact/SGcal) )
Liquid Viscosity Correction
Correct meter readings for liquids with viscosity above 1 cP
Reynolds Number
Determine flow regime (laminar, transitional, or turbulent) for a given pipe and fluid
Pipe Velocity & Flow Area
Calculate fluid velocity and pipe cross-sectional area from flow rate and pipe diameter
Pressure Drop (Darcy-Weisbach)
Estimate friction pressure loss through straight pipe runs for liquid applications
Pipe Schedule & Velocity
Look up ASME B36.10M pipe dimensions and calculate fluid velocity for any schedule and flow rate
Pipe Dimensions
Dimensions per ASME B36.10M. Velocity = Q / A. Recommended liquid velocity: 2–10 ft/s.
Unit Converter
Convert between common engineering units for flow, pressure, temperature, and pipe dimensions
