Hazen-Williams / Driscopipe

Hazen-Williams / Driscopipe

Hazen-Williams / Driscopipe

(OP)
All:

I need to use a calculated friction loss in a spread sheet.  This is a cool, clean fresh water application, so I assume Hazen-Williams will be reasonably accurate.  I have looked, but cannot find a ā€œCā€ factor for Driscopipe 1700 series.  The formula I plan to use is:

F = K * L (100/C)^1.85*((Q^1.85)/(D^4.8655))

Where:

F=Friction
K=Empirical constant (0.0009015)
L=Length
C=Friction factor
Q=Flow in GPM
D=Tubing ID

I would guess that C will be about 150 for Driscopipe.  Is that correct?

Any input or advice would be appreciated.
Thanks!

RE: Hazen-Williams / Driscopipe

According to a driscopipe CD I have the friction factor for all driscopipe is 150.  It is a few years old and doesn't have 1700 series on it but all others are 150
