sci.lfl-ufl-explosive-range Calculator
Calculates the lower and upper flammable limits of gas mixtures using Le Chatelier's mixing rule and estimates explosion hazard. Methane is flammable between 5% and 15% in air — below LFL it is too lean to ignite; above UFL it is too rich; the stoichiometric concentration (9.5%) is most explosive.
Inputs
Concentration Pct
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Lfl Pct
Reference formula or conversion factor shown for context.
Ufl Pct
Reference formula or conversion factor shown for context.
Flash Point C
Reference formula or conversion factor shown for context.
Temperature C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Results
explosion risk
Overall risk level based on the computed score or classification. Higher risk may call for mitigating actions or additional review.
concentration
The proportional relationship between two quantities.
flammable range width
The difference between the maximum and minimum values.
