CALCULATION:

(1604/(# OF MILS))*(%SOLIDS)

DESCRIPTION:

To get an estimate on the number of square feet a gallon will cover, the %solids of the material and the estimated number of mils being applied are required. Starting with the number 1604 (the theoretical number of sq.ft. 1 gallon at 1 mil and 100% solids would cover), divide by the number of mils desired. Multiply this number by the decimal form of the percent solids. As an example, using a product with 50% solids applying at 30 mils we would get: (1604/30)*.50 resulting in 26.75 sq.ft. per gallon.

REQUIRES:

  1. Mils to be applied
  2. Percent Solids of coating

UNITS:

Sq.ft. / Gallon

CALCULATION:

LENGTH*WIDTH

DESCRIPTION:

For a flat surface, i.e. a floor, wall, etc. the length and width/heighth are needed. Working in feet, multiplying these two numbers gives the square feet required.

REQUIRES:

  1. Length
  2. Width

UNITS:

Sq.ft.

CALCULATION:

PI*DIAMETER*LENGTH

DESCRIPTION:

The surface area of a pipe is calculated by multiplying the circumference of the pipe by the required length of work.

REQUIRES:

  1. Diameter
  2. Length

UNITS:

Sq.ft.

CALCULATION:

(LENGTH*WIDTH*HEIGHTH)/231

DESCRIPTION:

When filling a rectangular void, Length, Width, and Heighth are needed. Multiplying these gives the volume of the void. Working in inches, 1 U.S. gallon fills 231 cubic inches. Dividing the volume previously calculated by 231 gives the number of gallons required to fill this space.

REQUIRES:

  1. Length
  2. Width
  3. Height

UNITS:

Gallons

CALCULATION:

PI*LENGTH*( ((#1)/2)^2 – ((#2)/2)^2 ) /231

DESCRIPTION:

Calculating the annulus volume requires the internal diameter of the outer pipe and the exterior diameter of the inner pipe. For volume, the area of each pipe is found, multipled by the length to be filled, then the inner pipe is subtracted from the outer pipe.

REQUIRES:

  1. Outer Diameter
  2. Interior Pipe Diamter
  3. Length of work

UNITS:

Gallons
