PN means pressure rating of a pipe....PN is just a symbolic representation....
.pn was created in 1997.
PN Saxena was born in 1925.
Given an infinitely convergent sequence pn with limit p, the forward difference is the measure of the difference between the current term and he next. The backward difference is the measure of the difference between the current term and the previous.i.e.forward difference: Δpn=pn+1 - pnbackward difference: ∇pn=pn - pn-1Also, note that since they are both expressed by pn, the forward difference is recognised by the use of a delta before the pn, and the backward difference by the use of a nabla.

Pn-40,means pressure nominal for a valve
To find the length of segment PN when you know the lengths of segments PQ and QN, you can use the relationship that PN is the sum of PQ and QN. Specifically, if PQ and QN are adjacent segments along a straight line, then PN = PQ + QN. If they are not aligned, you would need additional information about their orientation to determine PN accurately.
