Thanks Jesse/Akshaya, I am trying to map the distribution area of treatment plants, I guess I will stick to the trace then!

Yes, the ability to choose the node type for automatic creation of nodes at endpoints in Modelbuilder is another request that's currently being evaluated. However the global morph tool in the next major release should also take care of this.

Regarding clash detection, please see below post:

The cpmbination system head curve only makes sense for an individual pump station.

One thing you can do is set up scenarions where different pumps are running at hour 0, 1,2, 3 etc at the station B when you run the combination curve for station A. The Set up a scenatio with differnet pump running at Station A when you run combination curves as station B. Show these miltiple time steps in you combination pump curves.

It is probably best to get the data from Florida's DOT and key in the rainfall curve.

I would probably just use WaterGEMS to compute the HGL at J-1 when PMP-2 is on and PMP-1 is off...

But you should also find that the HGL at J-3 is the same as the HGL at J-1. That's because there is no flow from J-1 to J-3 (so no headloss)...but they are still connected hydraulically so J-1 'sees' the HGL from J-3.

There was a bit of bad timing here. There is indeed a cumulative patch available for version 08.11.03.77 of our Storm and Sewer products (for SELECT subscribers), but it's currently in the process of being updated on our website. The updated version should be available shortly. Apologies for the inconvenience.

In the meantime, if a patch set is needed, you can contact technical support.

Thanks Jesse for feedback, I respect the technical issues in your side and hope be solved in short time.

the *._PatchLog.txt is the file I am asking about and that gives good details about where is the programs stand at. I hope that could be fixed and enable us to get full details.

Thank you for your help and insight, Scott!

I have one remaining question that I hope you may be able to answer. The "entrained water"--does this refer to the water that is inside turbine with the runner, or is it the water in the scroll case, the conduit that wraps around the and feeds water into the runner?

Thanks again!

It looks like the built-in turbine data assumes the 'rated' conditions are the same as the best efficiency point when the gates are 100% open.

Regards,

Mal

PS: I just tried to post new case but I am getting below message, and was not able to post, is that temporary and will be solved? how we can deal with that?

If you are still seeing that, please contact me offline and we will get this sorted out.

many thanks!

Hi Ben,

Noted, thanks for your reply!

Cheers

Good memories!

Samir,

To elaborate, the animation file format that you save to in the transient results viewer can only be opened by HAMMER. It can be useful if you want to send an animation to another HAMMER user.

For users without HAMMER, there are a number of screen recording tools available that can quickly save to a common video file format. For example, the animations you see in our Air Valve Technote were saved to the .gif file format using Camtasia Studio.

I think it's kind of neat that these docs reference back to Walski et al. (1994).

It's hard to get that kind of velocity, on the order of 1.5 m/s depending on slope. If the flow doesn't persist liong enough, you may not fill the downward sloping section.

Not only do you need air valve but you need to maintain them. They tend to get clogged up with grease and other nasty stuff and nobody wants to clean them. If neglected, they will seriously reduce the capacity of the force main.

I have bad luck as well with chart option, for example when I create system head curve, after change the x,y scale form Axes (in chart Option) maximum and increment and once close it and reopen the curve whatever I did of changes didn't get saved as well.

You get far more information for he same amount of input in the model as opposed to a srpeadsheet. You can see pressures, velocities, head loss and do all sorts of color coding to identifybottlenecks.

There is no special training needed. Just load it up as a water model with negative demands.
