How to simulate valves and fittings?

I was planning to use a coefficient. Is there a guide for coefficients for different fittings (valves, elbows, tees)?
I was also planning to use equivalent...

I have a pump with a shutoff head 76 m
However, when I run the simulation I get a head gain of 96 m
The pump is pumping from reservoir with 5 m head.

Why do I get a head gain of 96m (shutoff...

Thank you very much
I got the doubt because I got good results in the calibration; about 2 psi difference and identifying critical bad condition pipes with very low C (some already verified a leak...

I am performing some hydrant curve simulations. However, I got a doubt.
Fire hydrants also experience a local head loss.
Is there an option to include a local head loss in a fire hydrant node? Is...

Thank you.

One question. How do I apply a constant initial temperature?
The first time step I get one temperature (about 27 C), but from the second time step and the other it goes to 0. How can I...

I ahve some doubts when simulating water quality

*How do I define if I want to use first order decay or second order decay?

*When simulating water quality chlorine, how do I enter the...

InfoWater has the option to simulate water temperature (in water quality). However, it provide no information about the algorithm of data input.
What are the physical principles used to simulate...

Thank you.

I attach a video showing the bug (water age only shows 2 breaks). I attach a link because the video is quite big (90MB)...

I got some bugs using InfoWater v12.4

When I want to plot water age, the palette only has 2 colors (1 break). When I try to get additional breaks it always goes back to the default 1 break
I...

Thank you very much. Sorry, one more question.
I added the dummy loop with booster and pump. Results show 2 phases (attached image). A first phase in which chlorine tends to decrease. Then, it...

Thank you very much
One more question.
Are there any guidances for the float valve flow vs headloss curve? or each brand provides its own curves?

I have a tank and I want to include a floating valve

Without any valve the connecting pipe has a flow about 1000 cmd and a headloss about 2 m

The minimum tank level is 1m, and the maximum tank...

I would like to simulate one case where the chlorine in one strage tank is regulated every day. Every day at a given time, chlorine is regulated at given concentration (e.g. 1 mg/l).

I specify the...

I am preparing a mode
The model run ok, balances after 32 iteartions.
When I add 1 pipe connected to one node with demand zero, then the model does not balance. I increase to 200 iteration but...

Thank you Bob,

I sent you an e-mail

I am preparing a presentation. I want to present some capabilities of InfoSewer and SWMM (try to make a project).
I would like to add an animation showing results of simulation (2D overland flow and...

Thank,
I am using 12.4 Update 1

Other bug, is that sometimes I cannot visualize the water age. I can visualize flow, headloss, diameter and everything. But when I go to water age, it does not...

I updated InfoWater to v12.
However, I have a problem.
I successfully run a simulation. However, when I perform and try to run a simulation, it only refreshes the screen, but it does not show the...

I run a simulation, but when I go to the Map Display I get the error:

Read Data:System.NullReferenceException: Object reference not set to an instance of an object....

I have some water distribution models in InfoWater
I want to copy them to another computer. I copied the whole:
xxx.out folder
xxx.IWDB folder
xxx.mxd map

When I try to open them in the new...

I have a pipe that connects a city pipe connection with a tank (attached figure). The city connection is represented by a reservoir with a PRV.
Total head PRV = 118 m
Total head tank = 91 m

I want to use GIS Gateway to update original GIS data that was used to create a model.
In InfoWater I added new pipes and changed diameters. I would like to update the original GIS to reflect such...

InfoWater can be used to simulate the decay of contaminants such as chlorine. There are several reference guides about reasonable decay constant k for chlorine.
I would like to analyze the decay of...

I have a pump curve (attachment). The curve that is supposed to show the NPSH shows Flow vs Horsepower.
How can I input this curve? Do I use the curve type 4 (NPSH vs Flow)?
416

I get the following warning message:
WARNING unable to locate geometry data for pipe '460'
WARNING unable to locate information data for Junction 'J1502'

I get those same messages for other...
