Large Negative Pressure on model
Ir. Mohd Arzahri Abd Rahman
Hi, I am quite new to this software and am still in the learning process. I'd like to ask regarding a few uncertainties with my model which I believe are parts that I have missed out on. Firstly, I'd like to explain briefly on the background of the…

Partially Closed Valves in water supply system
levon batoyan
Hello, I'm modeling a high pressured water supply system full of partially closed valves (which people use as some kind of "prv's" to reduce pressure because they don't have enough money to buy it). The information they gave me is D(mm) of a valve,…

Pressure Spiking in WaterCAD system model
Noah Nieman
Hello All, I am modeling an existing system in WaterCAD version 10.03.02.75, where there are currently low-pressure problems in the far southern area because all the wells are in the northern area. When I run my model, the pressure bounces between low…

WaterCADD - Reservoir influence
Chris Sliger
I just recently started using WaterCADD. I am trying to model a system that involves pumping water out of the bottom of groundwater wells and into a collection tank. In order to supply water to the pumps, I am using a Reservoir (set at 1' above the pump…

WaterCAD 3D view
Igorich
Hello. Is there any way to get 3D view of WaterCAD model with pressure in every node showed as 3D cylinder or column sized depending on pressure value? It used to be in CyberNet water modelling software, but I can't find it in WaterCAD now. Thank…

Re: Field pressure readings upstream and downstream of PRV. HGL or not?
Mal Sharkey
Normally the gauges will give you gauge pressure. You need to accurately measure the gauge's elevation, and add that to the pressure reading to get the HGL. Also, if the gauge measures pressure (e.g. in kPa), you will need to convert that to pressure…

Re: HOW MODEL COMBINATION AIR VALVES?
Jack Cook
If someone wants to model only the cascading flow downstream of an air-valve; that is, the transitional pressure to gravity type flow that might set up in a gravity trunk main or a sewer forcemain, they should take a look at the new WaterGEMS/WaterCAD…

Re: Connecting Pipes with different pressures
Mal Sharkey
The connection betwen the 8 in and 12 in pipes sounds pretty straightforward. I would guess the way you have it set up in the model is fine, so long as it is a close representation of what's actually in the ground. If you have zero flow through the check…

Re: Pressure and Pressure Head, what are the differences?
Jesse Dringoli
" Pressure head " is the " Pressure " divided by the specific gravity of your fluid, which you can change in the calculation options. So, they will only be equal if the specific gravity is 1.0 (using the same units for both, such as feet or meters) …
