Cap Tube app help
Cap tube length recommendations provided by these applications vary to some astronomical extent despite being given identical conditions. I realize they are not intended to be exact but they should at least get you in the ballpark with cap tube length. for something so critical how is it that the apps aren't even close on their recommendations??
First DanCap. In the notes they describe no allowances being made for sub-cooling in the length of cap tube, but fail to disclose if any allowance has been made for normal sub-cooling up to the filter
next up is the Tecumseh version, which does allow entry of Sub-Cooling into the formula. But check out the more than double cap tube length compare to the DanCap recommendation
Removal of the Sub-Cooling from the equation resulted in a closer match of recommendations but still we're talking a cap tube where a few inches can have a marked effect on the load capability (at least that's my understanding).
Given that a colder fluid flows faster, it makes sense that the cap tube/restriction would need to be longer as shown in the Tecumseh version which also appears closer to physical cap tubes I've compared too.
but which one is correct/closest to the mark? PleaseLast edited by Indy2010; 07-02-2011 at 07:57 AM.
