Does anyone know Heastad's "Advanced Water Distribution Modeling and Management" book? I just wanted some reviews, if its a good book on your experience.
I'm doing calculations for how much water was lost when flushing a hydrant. It is a 2.5 in. outlet and the pressure is on the system is 40 psi. It was flushing for 1.5 hours.
Q=AV
V=[(2 dP gc)/density]^0.5
density = 62.4 lb/ft^3
dP=40 psi
gc=32.2 lbm ft / lbf s^2
V=77ft/s...
jajaja... na... its not a homework problem. I really appreciate your inputs, and I've been told about the Technical Paper a couple of times, so I guess I'll buy it. Now I think of some details that I could've left out, I'm going to do some math and I'll see what I come up with.
Thank you all...
Well... if the main 3/4" line is supplying 20 gpm, if I have 2 lines comming out, I'll have 10 gpm in each line, and if I have 3 lines comming out, I'll have 6.67 gpm in each line, won't I?
Yes, I'm assuming the pressure source will remain constant, thanks for that observation.
I guess...
Let's say that we have a 3/4" copper line to supply water. We have a volumetric flow of 20 gpm (0.0445 ft^3/s). With this, we have a velocity of 14.35 ft/s. Now, at the end of the copper line, I want to service two homes, so I split the service. Comming out of the 3/4" copper line, I have two...
