A steel pipe with an inside diameter of 10 in. will be used to transmit steam under a pressure of 800 psi. If the hoop stress in the pipe must be limited to 10 ksi because of a longitudinal weld in the pipe, determine the minimum satisfactory thickness for the pipe.

The minimum satisfactory thickness for the pipe is 0.4. in

Explanation:

The computation of the  minimum satisfactory thickness for the pipe is shown below:

As we know that

Now for determining the thickness we have to rearrange it

where,

p = pressure inside the pips

r = pipe radius

= stress of the hoop

Now put the given values to the above equation

So,

= 0.4 in

Hence, the minimum satisfactory thickness for the pipe is 0.4. in

The same is to be considered

can you make it more obvious. i can't see it properly
