Question

what is the inside diameter of pipe if the outer diameter is 2 inches and the wall thickness is 3/16 inch

Answer 1

The inside diameter of pipe is
`1(5)/(8)` inches.

Explanation:

Given:

The outer diameter is 2 inches and the wall thickness is 3/16 inch.

Now, to find the inside diameter of pipe.

Outer diameter = 2 inches.

Wall thickness = 3/16 inch.

So, to get the inside diameter of the pipe we put formula:

Inside diameter = outer diameter - 2 × wall thickness

`Inside\ diameter =2-2* (3)/(16)`

`Inside\ diameter=2-(6)/(16)`

`Inside\ diameter=(32-6)/(16)`

`Inside\ diameter=(26)/(16)`

Dividing the numerator and denominator by 2 of R.H.S :

`Inside\ diameter=(13)/(8)`

`Inside\ diameter=1(5)/(8)\ inches.`

Therefore, the inside diameter of pipe is
`1(5)/(8)\ inches.`
