Hi
In order to optimize the pipe diameter, I need to calculate the flowrate of water flowing freely from an open channel into a siphon pipeline of a given length and height difference between start and end. I do not seem to be able to do it with the available calculator. Typical values would be: Pipe diameter: 200mm, pipe length: 700m, height difference between start and end: 2m. Pipe material: PVC. Your help would be greatly appreciated. Regards Erhard

Re: Flowrate in siphon pipeline
Here is what I get with pressure drop calculator:
1. volume flow rate (q):
q : 1539.7335 l/min
2. weight flow rate (w):
w : 92384.125 kg/h
3. pipe length (L):
L : 700 m
4. pipe diameter (D):
D : 200 mm
5. pipe roughness (kr):
kr : 0.01 mm
6. density (ρ):
ρ : 1000 kg/m3
7. kinematic viscosity (ν):
ν : 1.006 mm2/s
8. dynamic viscosity (μ):
μ : 0.0010060001 Pas
9. K factor - minor losses coefficient (K ):
K : 0.5
10. velocity (V):
V : 0.8168556 m/s
11. cross section area (A):
A : 31415.928 mm2
12. friction coefficient (f):
f : 0.016659506
13. Reynolds number (Re):
Re : 162396.75
14. pressure on the pipe start (p1):
p1 : 12.328746 mWS
15. pressure on the pipe end (p2):
p2 : 10.328746 mWS
16. pressure drop (p1-p2):
p1-p2 : 2 mWS
