Calculate the outer surface area of a length of pressure pipe having a wall thickness of 2.3mm, with a inner diameter of 2.54cm and length 32m

Question

Please help solve

Answer 1

Hi Tyler, the surface area is given by: S = π * d * l, where d is the diameter and l is the length. It is necessary to change all measurements into one unit.

 

Working with meters:

 

Calculating diameter of pipe in meters:

 

Convert centimeters to millimeters:

 

2.54 * 10 = 25.4 millimeters

 

Diameter of pipe in millimeters:

 

2 * 2.3 + 25.4 = 30 millimeters

 

Diameter of pipe in meters:

 

30 / 1000 = .03 meters

 

 

Surface area of pipe:

 

S = π * d * l

 

S = π * .03 * 32

 

S ≈ 3.02 meters squared
