View Full Version : Using DIRCalc help

10-12-2007, 04:26 PM
Hello Guys,

I am currently learning to use the DIRCalc software for estimating pressure drop in existing NH3 system pipelines. Can somebody explain to me why increasing the liquid pump pressure lift decreases the dt? and what the dt is for if you have excellent insulation? The danfoss manual does not explain this.

Thanks for anyone who can help.
