The first difficulty in the way of the intellect’s functioning well is that it hates to function at all, at any rate beyond the point where functioning begins to require effort. The result is that when any matter arises which is properly the job of the intellect, then either nothing gets done at all, or else the imagination leaps in and does it instead. There is nothing to be done with the intellect until imagination has been put firmly in its place.

Dante,
Try the attached calculator, adjusting the "W/gpm" value to 11

Hello,

I have a general question redarging how to design HVAC pump with 11 W/gpm per primary and secondary loops in evaporator.

Please advise how a design can achieve that target. Most design that I have seen exceeds that limits becasuse it does not consider head.

Regards,

Dante
