Calculate slurry volume, percent solids, batch ingredients, density conversions, blend ratios, tank volume, and transfer time from your inputs.

Settled-resin percentage is a bulk settled-bed volume ratio. Density-based tools use true solid volume and assume additive volumes; the two bases are not interchangeable.

Slurry Volume Formula

The following formula is used to calculate the Slurry Volume. 

SV = Vgs × 100 / S
  • Where SV is the Slurry Volume (mL)
  • Vgs is the volume of resin settled by gravity (mL) 
  • S is the gravity-settled resin volume divided by total slurry volume, expressed as a percentage (%) 

To calculate a slurry volume, multiply the volume of resin settled by gravity by 100, then divide by its settled-bed percentage. A settled resin bed contains interparticle liquid; this ratio is distinct from dry mass percent and true solid volume percent. The density-based tools assume additive intrinsic component volumes. Transfer time uses the entered steady flow rate: time = volume / flow rate.

How to Calculate Slurry Volume?

The following example problems outline how to calculate Slurry Volume.

Example Problem #1:

  1. First, determine the volume of resin settled by gravity (mL).
    1. The volume of resin settled by gravity (mL) is given as 50.
  2. Next, determine the percent slurry (%).
    1. The percent slurry (%) is provided as 20.
  3. Finally, calculate the Slurry Volume using the equation above: 

SV = Vgs * 100 / %S

The values given above are inserted into the equation below:

SV = 50 * 100 / 20 = 250 (mL)


Example Problem #2: 

The variables needed for this problem are provided below:

volume of resin settled by gravity (mL) = 60

percent slurry (%) = 30

Entering these values and solving gives:

SV = 60 * 100 / 30 = 200 (mL)
