Sorry for bringing up an old thread.. all you guys have to do is ask nicely the password for the hpx tool is NIKOLASW .. the flow units are in KG/HR and the horsepower ESTIMATE is rear wheel.. I know these things as I am the one who wrote it.

 

oh yeah, and the tube size is O.D. so when you use 3.0 as a tube size the calculations are actually for 2.9" ID pipe

 

I think we had we had sorted out "back when" that the numbers were kg/h, not lb/h as stated in the lead in document--good to hear it from the "horse's mouth though.

Interesting.

Thank you for joining in, it's never too late...
