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
Depending on context, it could be an infra-red emitter. An emitter that emits at a wavelength longer than that of visible red. infra red emitter is a special pn juction device in which emitter region emits infrared rays
A pn junction can be formed by bringing the p and n type materials together.
Sarveshwar Dayal Saxena died in 1983.
PN is a pinch, just the amount you can fit between your thumb and index finger.
I cannot think of any, but a pn junction is a part of a diode and has a rectifying properties.
PN is pressure nominal. The number following is in bar = 14.5 psi/bar.
