General
Question: What if the fluid I am using is not included in the standard Pipe Flow Fluid Database?
Answer: You can add your own fluid details to the fluid database and these can then be used by the Pipe Flow program.
Pipe Flow Wizard
Question: Can Pipe Flow Wizard calculate flow rate?
Answer: Yes. When internal roughness, internal diameter, length, fittings, elevation change, and available pressure applicable to a pipe are known the FLOW RATE through the pipe can be calculated.
The type of flow, Reynold's number, friction factor, and fluid velocity are also displayed.
Question: Can Pipe Flow Wizard calculate pressure drops?
Answer: Yes. When internal roughness, internal diameter, length, fittings, elevation change, and flow rate applicable to a pipe are known the PRESSURE DROP through the pipe can be calculated.
The type of flow, Reynold's number, friction factor, and fluid velocity are also displayed.
Pipe Flow 3D
Question: Can I extract the results into a spreadsheet?
Answer: If you click on View->Pipe Work Listing this will show a spreadsheet type view of the pipes and details. Now click on Edit and select 'Copy all to clipboard' - you should now be able to paste this data into Excel.
Question: I have a pump with a balanced four nozzle distribution system. I can use an open pipe end and set a "k" factor for my nozzle (fire sprinkler head). Do I have to manually establish the flow rate through each pipe in the network? Is there a method that I am not using whereby the software will calculate my flow and pressure losses through the system by establishing the pump output conditions?
Answer: Pipe Flow 3D does not automatically establish the outlet flow between the various branches in the system.
The user must specify the flow rate for each pipe.
The easiest method of setting the flow rate for each pipe is to set the flow rate in the pipes leading to each outlet point. When you click on the system analysis tab the flow check warning will appear if the flow rate through a pipe does not match with the following dependant pipes.
Click OK to set all flow rates to match the requirements for the outlet flows.
You can use the 'Adjust all flow rates' option to change all flow rates to suit a new overall flow rate, or a new pump outlet condition - the flow rates are adjusted on a percentage basis, maintaining the relative ratio between the flow rates in each pipe.
You may be able to use these 'what if' features to try and find a solution to your problem.
