    Details of Time To Fill Calculator

    by Titus Nelson, PE

    Inventor of the Holey-Moley Digger

    Use the Time To Fill Vacuum Drum Calculator to determine the Total Weight of the soil inside your vac.  Input (gallons) and Select Soil Type for Density and Soil Type for Swell factor.

    In addition, the anticipated soil weight can be helpful when Selecting The Best Hole Digging Shop Vacuum and for determining the size of a shop-vac for digging holes.

    Finally, see the blog page on Digging Deep, Straight, Uniform Holes with a Shop-Vac for relevant information.  We love feedback, let us know how you like these calculators.  If you would like to be kept up-dated on blog articles please sign up for more information here.

    This calculator outputs the hole volume in cubic feet and gallons, soil weight in pounds, based on selected soil densities and input hole dimensions. It also provides removed soil volume based on selected soil swell factors.

    Input – Gallons for volume of vacuum container.

    1. Input number of gallons

    Input – Lift Rate (lbs/sec)

    2. Input lift rate in lbs/sec.   This can be determined by using a 5 gallon container filled with the material (weigh it in pounds).  Then use the vacuum to suck the container empty and measure the time it takes.  The number you want is the lift rate in pounds/second.

    Select – Soil or material Density in Drop Down

    3. Select material Density Drop Down for the material in Shop Vac

    Select – Soil or material Swell Factor in Drop Down

    4. Select the Swell Factor Drop Down for material in Shop Vacuum (use same material selected for Density

    Output (Weight)

    1. Total Weight – Pounds

    2. Time to Fill – Seconds

    3. Time to Fill – Minutes

    Summary

    This Time To Fill Calculator makes it easy to calculate the amount of time it will take to fill a vacuum container with selected material and the total weight of the soil or material in the vacuum container.

    Because soils are surprisingly heavy, it is helpful to know how fast your container will be filled and the weight you are dealing with inside your vacuum container.  This will help prevent damage and prevent back injury from moving a heavy weight
