How many pipe(s) can I paint with 5 litres of paint?

I think we need more info??? Like how much area a certain amount of paint (one can/litre perhaps?) will cover.

Surface Area Cylinder (pipe) = 2(pi r sq.) + (2 pi r)* h

It has no ends so just - (2 pi r)* h

When you find the area of one pipe (and if you know how much you can cover with 5 litres) you can do the division - Amount 5 litres can cover divided by the area of one pipe.

Edit:

Thanks for the extra info. So...

Area of 1 pipe -

(2*pi*r)*h

=78*600

=47123.89 cm sq.

Area Covered by 5 litres (at thickness of 0.01cm)

We know the volume of paint and height to which it should be applied - we have to find the area it will cover.

V=surface area x height

5000 = A x 0.01

A=5000/0.01

= 500,000 cm sq.

This is the area 5 litres will cover - now divide by the area of one pipe to see how many you can paint.

500000/47,123.89

=10.61 pipes

So 10 pipes.

What thickness do you want? Will the paint be applied by spray gun or brush. Just two more variables in the question.

don't have the what kind of paint best i can tell 39 pipes best i can tell,,, thx and have awonderful day

complicated aspect. query at yahoo or google. just that can help!
