Thank you!

[@lostinlife5154]

Abhishek Sir... I wanted to ask why value of "m" is > 1 I mean how gasket can apply more pressure on flange than it is subjected to. I mean if internal pressure is 5 kg/cm2 how gasket (having m=3) is applying 15 kg/cm2 ? Logically it should damp some pressure. Right ?

[@danielodeliro2412]

Thanks

[@jasonligo895]

I would think that adding Wm1 and Wm2 would be the total force that the bolts would need to exert in order for a gasket to not leak at a specific operating pressure?

[@ScootoideLearning]

Both are different cases.

[@shridharjakhalekar5002]

Why there is multiplication by 2 in Wm1 but not in Wm2?

[@majidalkhayari5572]

I do not understand from where the 2 came in Wm1 eq but I do understand why it is not there in Wm2 eq. G×pi = mean circumference of the gasket so when he turned it into a rectangle it became the rectangle length. b is gasket width, practically it is OD-ID of gasket if I am not getting this wrong

[@ManojKumar-vf4gf]

2 faces of the gasket

[@atishjain7093]

No 2 gasket faces does not means 2 times force will be taken. Reaction force always be there.

​@@majidalkhayari5572 Hey dear, So basically according to what I know "b" is just the half width of the gasket. hence to calculate the area we have to take 2b * circumference.
