CALCULATORS / PROCESS AND CIVIL

Process and chemical engineering estimates

Specified chemistry and low-order mass/energy balances.

inlet/outlet streams, compositions, accumulation assumption → missing stream or composition

source concentrations, volumes or masses, density convention → final concentration, blend quantities

balanced reaction, reactant quantities, conversion → limiting reagent, theoretical product quantities

pressure, volume, amount, temperature → missing ideal-gas state variable

composition, molecular masses, pressure, temperature → molecular weight, ideal density, partial pressures

working volume, volumetric flow, operating basis → nominal residence time

batch masses, heat capacities, temperature change, losses → energy, heating-time estimate

area, pressure, viscosity, calibrated resistance parameters → conditional filtrate/time estimate

diffusivity, geometry, distance or duration → characteristic diffusion length or time

reaction amount, enthalpy, conversion, heat capacity → heat release/absorption, ideal temperature-change estimate
