It is simple to understand. Thanks @Yasir sir.

The design of a pressure vessels is on the basis of Hoop Stress. So,
Hoop Stress = pd/2t, convert diameter into mm because all other units are in mm and then solve you will get 25 mm.
1*1000/2*20 = 25 mm.
Hoop Stress = pd/2t, convert diameter into mm because all other units are in mm and then solve you will get 25 mm.
1*1000/2*20 = 25 mm.

Here d is in m so convert it into 1000mm.
Then 1000/(2*20)=25mm.
Then 1000/(2*20)=25mm.

@Noman Ahmad Khan.
It's 1000 not 100.

Pd/2t.
Then 1 * 100/2 * 20 = 25.
Then 1 * 100/2 * 20 = 25.
