## 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.
