V=(πD2/4)h where D is the diameter of the 55 gallon drum and h is the height of the oil. Or if you prefer V=(2πr2h where r is the radius of the drum and h is as above.
14.37 psi is 0.20317789 inches of mercury.
Height = 36 inches (3 feet) Diameter = 21 inches
12 gage
18 inches
The micron is 1 x 10-6 meters, so 5 microns is 5 x 10-6 meters. This is also 0.005 millimeters, or 0.000197 inches.

Gallons is a liquid measurement and inches is a solid measurement so there is no such thing as inches in a gallon but there is square inches in a gallon which is completely diffrent. Cubic inches measure volume so a gallon would be measured in cubic inches rather than square inches. 231 cubic inches is equal to one gallon.

Unfortunately, there are NOT square inches in a gallon - they are CUBIC inches (a measure of volume, not area)
