User Guide

This tool will calculate the amount of time required for a quantity of substance mass to transfer at a specified flow rate. A conversion chart showing a range of mass versus flow rate values will also be shown for each set of input parameters.

Formula

The mass flow rate formula used by this calculator is:

t = m / ṁ

Symbols

• t = Time
• m = Mass
• ṁ = Mass flow rate

Mass Required

Enter the total mass required and select the appropriate units.

Mass Flow Rate

Enter the average flow rate expected to be maintained during transfer of the required mass.

Elapsed Time Calculation

This is the amount of time it will take to accumulate the required quantity of mass at the specified average flow rate.
