how to calculate surface area of pipe?

how do i calculate the surface area of a pipe whose dimensions are as follows:

Pipe Size [O/D] = 355.6mm

pipe lenght =60mtr

surface area of pipe= ?

    $ surface area of a pipe=circumference*Length

    $ surface area of a pipe:

    =pi*Diameter*Length

    =3.14*[355.6/1000]*60

    =66.99504

    =66.96 meter^2

    [If you develope the pipe , you will get a rectangle as per your data.

    Area of rectangle=length*breadth

    here, breadth of pipe=3.14*Diameter]

    [Outside Surface Area of Pipes:

    Outside surface area of steel pipes can be calculated as

    Ao = 0.2618 do

    where

    Ao = outside area of pipe - per foot (Square Feet)

    do = outside diameter (inches)

    Inside Surface Area of Pipes:

    Inside surface area of steel pipes can be calculated as

    Ai = 0.2618 di

    where

    Ai = inside area of pipe - per foot (Square Feet)

    di = inside diameter (inches)

    Yes, it appears that even in this very simple case the calculation of the surface area of the pipe would involve some fairly meaty calculus. But there are two quite easy theorems, known as Pappus's centroid theorems (the first gives the surface area of the pipe, the second its volume) which make the calculation a doddle even in the general case. The first states that if the curve representing the cross-sectional shape of the pipe - in this case obviously a circle - is rotated about an axis in the plane of the curve but external to it, the area of the surface of revolution produced (ie that of the pipe) is given by the product of the length of the curve and the distance travelled by the centroid of the curve. In this case the cross-section of the pipe is a circle of radius r and hence length 2.π.r which is rotated about an axis at a distance R from the centre or centroid of the circle. If the axis is rotated by one-quarter of a revolution, to produce a 90° bend in the pipe, the centroid has travelled a distance (2.π.R)/4 = π.R/2, and the surface area A of the pipe produced is given by A = (2.π.r).(π.R/2) = π².r.R Note that r is the external radius of the pipe, ie half the OD, if you require the external surface area, or the internal radius (half the ID) for the internal surface area I can't calculate the surface area A for the pipe in the question, as you haven't given a value for the radius of curvature R of the pipe, but I'm sure you can do this without problems for any values of r and R you wish to select. Moreover, this general method works for any cross-sectional shape of the 'curve' eg ellipses, polygons and even irregular shapes, as long as you can work out the position of the centroid. HTH
