The lower viscosity at 180 allows a higher flow. I am away from my reference books, but will try to look up the effect in a couple of days.

Hi Bill,
I was just looking at the viscosity of water. It varies from 1.31 cp at
40 deg to 0.347 cp at 180 deg. What does that do to the flow rate
everything else staying the same?

Bob,
Pressure drop through a core is usually linear with the square of the
flow rate, both for pumps and radiators.
The point marked "real rad test" has my two evap cores in parallel
being pumped by the mazda pump.
Pumps in series add pressure, pumps in parallel add flow rate.
