Really? I saw 0.132
...and he still used an Eheim 1260, giving the strange results of the block having a higher pressure drop than the PolarFlo, but also receiving higher flow rates than the PolarFlo, due to the 1260's better ability to deal with pressure drops when restricted.
i.e. JoeC is reporting different points on the pressure vs C/W curve as if they all correlated and were equal. Not saying that the difference would be dramatic, but he has slightly biased the results
against all the other blocks he's tested to date.
One would predict flow rates of around 0.85GPM if he had used the 1048, which may correspond to a ~0.005C/W difference, or enough for JoeC to report a 0.14C/W value instead.
Very curious measurement methodology that he has going on there.
Maybe BillA might like to have a word with him about what he's doing.
