Second, what are the coolant temps? Without knowing the coolant temps of each liquid, the test is useless... sorry to be a stick in the mud, but we need more info to make a proper determination.
on the other forum, 123Bob is going to record the coolant temps. Also, when looking at the numbers you have to look at all the numbers. If you are going to do an entire balance on the system, the radiator intake/exhaust temps will come into play. Of the 9 intake temps 8 were hotter on the nanofluid tests, but the deltaT across the radiator was lower on all the tests (if you average the three deltaTs for each test). You can crunch thru the numbers and get a good approximate coolant temp because the system will be in steady-state. If it wasn't it would either continue to get hotter or colder. And, the heat removed by the radiator is going to be close to the heat picked up by the coolant as it passes over all the components. Of course, you have residual losses thru the tubing etc, so it won't be exactly equal.

But, you are correct in that the coolant temps will tell a lot.
