Hydronic Balancing Part 4: How to Develop a System Curve
/What is a system curve and how is it used to develop a balanced hydronic system?
The “system curve” is a graphical representation of the head losses and gains of a particular piping system that result from changes in flow. And it’s all based on this law:
As you double the flow through the piping the pressure drop increases by the square. In other words, the pressure drop increases by four times what it was.
