How many liters of paint do i need to paint a one meter 25mm dia pipe?

Very little. The surface area of the pipe is only


2.5 蟺 * 100 = 785 cm^2





For paint coverage, I found a figure of 1 gallon of paint to cover about 350 square feet, according to

This is for painting walls, but it gives us an order of magnitude, and translates to 1 litre covering 71621 cm^2 (assuming it is a UK gallon). So you will need about 10 ml for each coat of paint.How many liters of paint do i need to paint a one meter 25mm dia pipe?
You need to know how thick the wet paint will be applied. The area is


0.25 蟺 * 1 = 0.785 m^2 = 7850 cm^2 . Multiply this by the thickness of the wet paint in cm to get cm^3 and divide the result by 1000 to get liters.
