- Formula for Prestart Powder
Diameter. of bag in inches X 3.14 X length of bag in inches X quantity of bags divided by 144 = total sq. ft. of filter cloth area. Since 1 lb. of prestart powder per 20 sq. ft. of filter cloth is required, then divide total sq. ft. by 20 to give you the total amount of pounds required for test.
