For our purposes here let us base our Rates on Pounds or Kilograms per minute with
one decimal place (DDD = 10). We need the number of pulses per Pound or
Kilogram so from the information above we calculate

When working in pounds we can determine pounds per stroke or strokes per pound.

Pounds per Stroke Calculation – assume nine (9) pounds per gallon - check the Data
sheet or MSDS sheet for your actual weight.

Multiply the weight per gallon by the gallons per stroke (from above chart) by

Resin weight per Unit (Pounds per gallon) –

9.00 (insert your actual weight)

Gallons per stroke –

x 0.03147 (from chart above MLS-4600)

Pounds per stroke –

0.28323

Now convert that to Strokes per pound –

1.00

0.28323 (pounds per stroke)

= 3.5307 (strokes per pound)

Now to determine pulses per pound multiply by the number of strokes per pound by
the number pulses per stroke. For our purposes here let us assume four (4) pulses per
stroke.

Strokes per pound –

3.5307

Pulses per stroke – x 4.00
Pulses per Pound – 14.1228 (round to 14 Pulses per Pound)

Kilogram per Stroke Calculation – using Specific Gravity: if you know the specific
gravity of the resin you can find the weight of the resin in grams by multiplying cc (cubic
centimeter) by the specific gravity (cc’s to grams, multiply by specific gravity). Based on
the example above we can know the specific gravity is 1.08 (9 pounds (1 gallon of resin)

8.33 pounds (1 gallon of water) = 1.08 specific gravity)

Multiply cc per stroke by the specific gravity to get gram per stroke –

Cc per Stroke –

119.1553 (from the chart above MLS-4600)

Specific Gravity – x 1.08
Grams per Stroke –

128.6877

To convert that to Strokes per gram –

1.00

128.6877 (grams per stroke)

= 0.00777075 (strokes per gram)

Multiply by 1000 to get Kilogram –

7.77075 (strokes per kilogram)
