Answer:

8 mm

Step-by-step explanation:

Given:

Diameter, D = 800 mm

Pressure, P = 2 N/mm²

Permissible tensile stress, σ = 100 N/mm²

Now,

for the pipes, we have the relation as:


\sigma=\frac{\textup{PD}}{\textup{2t}}

where, t is the thickness

on substituting the respective values, we get


100=\frac{\textup{2*800}}{\textup{2t}}

or

t = 8 mm

Hence, the minimum thickness of pipe is 8 mm
