This Time To Fill Calculator computes the time it takes to fill a vacuum container with selected soil types and the total weight of the vacuum container when full.

## Details of Time To Fill Calculator

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
