SteamPro Suite – Industrial Steam Calculators

SteamPro Suite

Industrial steam calculators for chemical, petrochemical, and oil & gas facilities. Paste into an Elementor HTML widget—no build tools, no React.

Interpolated mini-table (engineering estimates). For design sign-off, verify with IF97.

Pressure bar(g) Absolute add-on bar

Tsat— °C

hf— kJ/kg

hfg— kJ/kg

hg— kJ/kg

Assumes bar(g) → bar(a) by adding the absolute offset (default 1.013). Adjust for site altitude if needed.

Q = m·hfg (saturated steam). Add sensible loads separately for subcooled condensate.

Heat Duty Q kW Steam Pressure bar(g)

hfg (from saturation)— kJ/kg

Condensate rate— kg/h

Condensate rate— kg/s

For superheated supply, cool to Tsat first: Q_total = m·(c_p·ΔT_superheat + hfg).

Flash % = (h₁ − h_f2) / h_fg2 with h₁ ≈ h_f1 for saturated condensate at P1.

Condensate Flow kg/h P1 (Cond. press) bar(g) P2 (Flash press) bar(g)

Flash fraction— % w/w

Flash steam— kg/h

Assumes negligible heat loss. If condensate is subcooled, use actual temperature for h₁.

Ideal-gas density ρ ≈ P/(R·T), R_steam=461.5 J/kg·K. Choose velocity by site standard.

Mass Flow kg/h Pressure bar(g) Temperature °C Target Velocity m/s

Steam density (ideal)— kg/m³

Volumetric flow— m³/s

Required ID— mm

Velocity (calc)— m/s

Extend with Darcy–Weisbach and fittings K for pressure drop checks.
