here is one so curious that I ran some addl points to confirm
http://www.thermal-management-testing.com/80diss.gif
this curve will shift when I re-do, the tail will rise, but even so

The tail is a puzzle; if not measurement error(re. Incoherent) or frictional heat(would require dP=18+ m(H2O))

Has driven me to look(again) at flow-boiling ( "the bends", cavitation)
Only got as far as :
"For the dissolution of oxygen in water, O2(g) <--> O2(aq), the enthalpy change under standard conditions is (-11.7)-0 = -11.7 kJ/mole"
O2(aq) possibly drops 0.83 mg/l per m(H2O) dP across radiator when no temperature change temperature.(Calculator)

Looks a tortuous road, to retread after 45 years, to yield nothing .
Looks more like pHaestus's territory.
