Understanding our Iligan's Suarez cPVC water pipeline:
Camp Pintoy to NSC junction,
Length/Expansion
L=2.8km
∆L=7mm/10m at 10°C drop
∆L=1.96m, theoretical pipe expansion/elongation...too much thermal stress if no Expansion joints...mapotol ang mga sinumpayan (one at a time, matira ang matibay🪓✌️).
Head/Elevation difference
H=90m
p=sgH=62.43 #/ft3x90m
p=128 psi
Assuming that our pipe is a SDR11, PN16
PN16=16bar or 230psi pressure rating >> 128psi.
No issue in pipe quality.
Excessive pressure make longitudinal crack.
Bason masabtan kon excessive pressure ba ang hinungdan o kulang/walay Expansion Joints.
Ang dunay ika tampo, comment lang. Please technical ra, walay political 🙏🙏🙏.
