Martins calculator presumes the same as me that 2 pumps will have twice the head but the same flow.. i believe this wont be reality though, which is why it would be nice to get some trust worthy to test the different configs
On Martins calc you'll get more % of flow, depending on restriction of course, the more restrictive the loop the more the % flow you'll get with a second pump. If your running a real free flowing block a second pump wont do much for you since it's not using any of it's extra head from the second pump, it would just be more heat dump with no gain. Even using the low restriction set up he has already on the estimater adding a second pump is good for a little over a half gallon more flow per minute. Stick the double inpact in its place and add a second pump the % of flow gain goes up. But that's old news everyone already knows that.
|Yeah those series tests are useless to me cos i want to know the head and flow of the 2 pumps .. not how much more they flow around a loop a loop with black and rads in them .. It's interesting though
You mean on the DDC tests? He has all the head and flow charts there. But I guess you mean for the serial or parallel loops.
EDIT: Yeah I saw you on the last page or two there, I'd forgotten about that. That used to be a real good site before the break-up in 2005.Edited by ira-k - 8/27/09 at 2:46pm
