User Guide

This tool will calculate the average mass flow rate of a gas or liquid in any units from the total mass of gas or liquid which has been transferred over a specified of period time. Once a flow rate has been calculated two conversion tables will be displayed for a range of mass and time periods centered around each calculated flow rate.

Formula

The mass flow rate formula used by this calculator is:

ṁ = m / t

Symbols

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

Mass Transferred

Enter the total mass of gas or liquid that has been transferred and select the appropriate mass measurement unit.

Time Taken

Enter the amount of time that passed for the quantity of gas or liquid that has been transferred. Select the appropriate units of time.

Mass Flow Rate

This is the calculated average flow rate of the gas or liquid expressed as a quantity of mass per unit measurement of time.
