head Loss & discharge comparison for 2" (60 mm OD) Dutron Standard
Column pipes & Gl pipe for installation at 450ft (137 meters) depth.
Considering that water will not be lifted higher than the ground level
(i) Head Loss due to depth of pump =137 meters = 450 ft both incase of Dutron Column pipes & steel pipes.
(ii) Head Loss due to friction in Dutron Column pipes as per technical chart-4
taking working range of discharge as 18m3/hr for
18m3/Hr=300 lpm
As
per Technical chart 4 frictional head loss is= 7.71 meters/100 meters
of depth for 2" (60 mm Dutron Standard Pipes For 137 meters frictional
Head loss 137/100 X 7.71 = 10.56 meters
Total head load on pump with Dutron Column pipe = 137 + 10.56 = 147.5meters
(ii) Head loss due to friction in Steel pipes As per Technical chart 5 = 21.12 mtrs/100 mtrs
For 137 meters frictional =137/100 X 21.12 mtrs.
Head loss = 28.93 mtrs.
Total head load on pump with Steel pipes = 137 + 28.93 =165.93 mtrs.
In the same working condition the head load on pump is different than case of Dutron column pipes and steel pipes.
As
per pump chart 10% to 30% extra water discharge is available with
Dutron column pipe in comparison to steel pipes depending upon depth
and discharge of pump
This means great power saving and less pumping time.
2) Even combination of Dutron Standard and Heavy pipes have lesser frictional Head than steel pipes.
It has been debated that Dutron heavy pipes have lesser Internal
diameter because of more thickness and therefore water discharge will be
less in comparison with seal pipe.
Comparison
of Technical chart 4 & 5 shows that Dutron Super Heavy Pipes also
have lesser frictional loss compared to steel pipes. Even 2" super
heavy pipe has almost 33% lesser frictional loss than 2" steel pipe.
