Internal Reflux Ratio Based on Liquid and Distillate Flowrates Solution

STEP 0: Pre-Calculation Summary

Formula Used

Internal Reflux Ratio = Liquid Reflux Flowrate/(Liquid Reflux Flowrate+Distillate Flowrate)
R_in = L/(L+D)
This formula uses 3 Variables

Variables Used

Internal Reflux Ratio - Internal Reflux Ratio refers to the ratio of liquid refluxed back to the column and the amount of vapor flowing out from the top of column.
Liquid Reflux Flowrate - (Measured in Cubic Meter per Second) - Liquid reflux flowrate refers to the amount of liquid returning or flowing back in a distillation process.
Distillate Flowrate - (Measured in Cubic Meter per Second) - The distillate flowrate refers to the rate at which the distilled or separated product is collected during a distillation process.

STEP 1: Convert Input(s) to Base Unit

Liquid Reflux Flowrate: 1.2547 Cubic Meter per Second --> 1.2547 Cubic Meter per Second No Conversion Required
Distillate Flowrate: 0.875264 Cubic Meter per Second --> 0.875264 Cubic Meter per Second No Conversion Required
