Use this engineering calculation for a transparent preliminary estimate or independent arithmetic check when geometry, materials, loads, operating conditions, and units are defined consistently.

Inlet Moles Per Second (mol/s)

Required number input.

Outlet Moles Per Second (mol/s)

Required number input.

Single-reactant chemical conversion fraction from inlet and outlet molar flow rates on a consistent basis. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Conversion Fraction

The resulting conversion fraction returned as a number.

• Conversion depends on kinetics, temperature, pressure, residence-time distribution, mixing, catalyst state, equilibrium, heat and mass transfer, and reactor model. A scalar conversion is not a complete reactor or safety design.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check assumptions against drawings, measurements, current material data, and the applicable design code. Apply required load combinations and safety factors, then obtain qualified review and testing for consequential designs.

• BOD Removal Efficiency

  BOD removal percentage from influent and effluent concentrations sampled on a comparable basis.

• Venturi Flow Rate

  Incompressible Venturi flow from inlet and throat area, pressure difference and discharge coefficient; requires throat smaller than inlet.

• Bernoulli Total Head

  Total ideal-flow head as elevation plus pressure head and velocity head; excludes friction and pump terms.
