I build municipal water plants and I want to check the design engineers work before I buy the material and put in the ground. Invariably if their design doesn’t perform as it was supposed to, then they attempt to blame the contractor instead of owning up to a bad design.

It would be great if I could take Line A, a 72″ steel pipe, insert X number (up to 10) of bends (and their degrees), elevation differential, valve types & number, flow meter type (shape), etc in order to check the hydraulic profile of Line A and then be able to string multiple lines to understand and check thea. Basically, some (very expensive) pumps need a certain amounts suction and/or discharge pressures at certain velocities to work at their most efficient range possible and in a way that does not cause cavitation and long term pump damage. Pumps are/or piping systems are obviously much cheaper to correct prior to installation as rework means endless meetings to toss blame and assign costs and or damages. Good data to backup my arguments for such a change in the design is essential. If you can help, you are the man.

Something like this, but updated.

I still need to work on an update to automagically select the pipe size based on diameter and schedule. This will be coming next year as it will take some time to ‘redo’ the app. Thanks again for your comments.

It would also be nice if pump manufacturers release pump curves and O/M manuals as ipod apps. It would be cool to pull up a pump curve in front of your client while you guys were looking at the pump.

I would love to hear from you soon, and I have more ideas that I would love to see happen. I wish I had the time to learn Mac programming so I could make the apps myself.
