Ngo ma obedo "inch": Inch (") obedo gin ma ki ngeyo pi jami ma ki tiyo kwede i lobo Amerika, ma calo paip ma ki yubu ki nyonyo, valves, flanges, elbows, pumps, tees, ki mukene, ma calo gin ma ki keto ni 10′′.
Inches (inch, ma ki coyo ni in.) tere ni lwet cing i leb Dutch, ki inch acel tye bor pa lwet cing. Ki lok ada, bor pa lwet cing dano bene pat. I cencwari me 14, Rwot Edward me aryo okati ki "cik ma ki ngeyo".
Ki waco ni bor pa nyig cam adek madongo ma ki yero ki i dye nyig bel ma ki keto i rwom acel tye inci acel.
Pol kare 1′′=2.54cm=25.4mm
Ngo ma obedo DN: DN obedo gin ma ki tiyo kwede i yub pa jo China ki lobo Europe. En bene obedo gin ma ki ngeyo me ngeyo paip, valve, flanges, paip fittings ki pumps, ma calo DN250.
DN nyutu dit pa paip (ma ki ngeyo bene ni diameter ma ki ngeyo), nen: man pe obedo diameter ma woko onyo diameter ma i iye, en tye i kin diameter ma woko ki diameter ma i iye, ma ki lwongo ni average diameter ma i iye.
Ngo ma obedo Φ: Φ obedo gin ma rwate, ma nyutu dit pa paip, cing, nyonyo ma rwate ki jami mukene. Ki twero waco ni tye diameter. ma calo, Φ609.6mm nyutu lac ma woko ma tye 609.6mm.
I kare ni ma dong waniang ngo ma dul adek eni nyutu, ngo ma kubbe i kin gi?
Mukwongo, "Tyen lok pa "DN" rom ki pa DN, ma nyutu dit pa gin ni, ma nyutu dit pa gin ni, ki Φ tye me ribo gin aryo ni.
ma calo: ka paip ma ki yubu ki nyonyo tye DN600, ki paip ma ki yubu ki nyonyo ni ki keto lanyut iye ki inci, en doko 24′′. Tika tye wat mo i kin jami aryo magi?
Lagamme tye ni ee! Inci ma rwate ki wel ma ki medo ki 25, ma rom ki DN, ma calo 1′′*25=DN25 2′′*25=50 4′′*25=DN100 ki mukene.
Ki lok adaa, tye mukene ma pat pat, ma calo 3′′*25=75, ma ki rwate ki DN80 macok, ki inci mogo ma tye ki semicolons onyo decimal points, ma calo 1/2′′ 3/4′′ 1-1/4′′ 1-1/2′′ 2-1/4′′ 1-1/2′′ 2-1 /2′′ 3-2′′ 3-1/2′′ kit meno, pe kitwero kwano kit meno, ki mukene. ento wel ma ki kwano ni rom, wel ma ki waco ni:
1/2′′=DN15 3/4′′=DN20 1-1/4′′=DN32 1-1/2′′=DN40 2-1/2′′=DN65 3-1/2′′=DN90
