piping system simulation
piping system simulation
(OP)
For my personal education I would like to develop the math system (differential equations?) to simulate a simple home water supply system.
System Description
Well or tank supply (various water levels)
>pump c/w pump curve
>bladder expansion tank (PV relationship)
>piping friction losses
>water tap discharge at different flow rates
A active variable plot during system operation would be nice.
Any recommendations on where to start? Thanks.

RE: piping system simulation
* Level of detail
* Accuracy you want
* List your assumptions
* Load cases you want to look at
Sketch typical system of interest and label nodes
Roll up your sleeves and go to work

And do you want a steady state or dynamic model?
Matlab / Simulink is good software to solve differential equations and make dynamic simulations.

Feel free to use part of my program if you wish.
Good luck and happy learning!!

<General> As this is a learning exercise I would like to create/setup the differential equations myself
so a paper or textbook describing this would be an asset.

There a several good books on the mathworks site i.e.
Computational Methods for Process Simulation
W. Fred Ramirez
This book presents a time-domain approach to modern process control and is written for students and professionals in chemical, control and instrumentation, and process control engineering.

What you typically need to do is to set-up the dynamic mass and energy balance of the tank-pump-pipe system.
Some of the (steady stae) equations you are looking for can be downloaded from my website: www.carf-engineering.com
Hope this helps,
