Basic Calculations for determining the mass of VOC emitted.

VOC Calculators

There are four separate calculators on this page. They are

VOC, HAP Emissions Per Gallon of Coating Less Water Where the Weight of Water per Gallon is Known
VOC, HAP Emissions Per Gallon of Coating Less Water Where the Percent Water by Weight is Known
VOC, HAP Emissions Per Gallon of Solids
VOC, HAP Emissions Per Weight of Solids

A complete description of each calculator is presented in the document Understanding and Using the PCRC VOC Calculators. Make sure to read that document first.

Calculator 1. VOC, HAP Emissions Per Gallon of Coating Less Water Where the Weight of Water per Gallon is Known. (See next calculator if per cent water is known)

Enter the weight per gallon (pounds) and the density (pounds/gallon) (Use this handy units conversion calculator) for each non-VOC or non-HAP in the formula.

	non-VOC/HAP Lbs/Gal	Density
Water

Calculator 2. VOC, HAP Emissions Per Gallon of Coating Less Water Where the Percent Water by Weight is Known.

Enter the weight (pounds) per gallon for each VOC or HAP in the formula.

VOC/HAP

Enter the weight per gallon (pounds) and the density (pounds/gallon) (Use this handy units conversion calculator) for each non-VOC or non-HAP in the formula. Calculator 3. VOC, HAP Emissions Per Gallon of Solids.

non-VOC/HAP	Density






Enter the percent water (by weight)(enter a number from 0-100):
Enter the density (lbs/gal) of the coating (can be derived from specific gravity, spec. gravity times 8.3 equals density in lbs/gal):

Enter the weight per gallon (pounds) for each VOC or HAP in the formula. (Use this handy units conversion calculator).

VOC/HAP Lbs/Gal	Density

non-VOC/HAP Lbs/Gal	Density

Calculator 4. VOC, HAP Emissions Per Weight of Solids.

Enter the weight per gallon (pounds) for each VOC or HAP in the formula. Enter the weight per gallon (pounds) for the total solids in the formula. (lbs)
