Okay, I created this topic because the other one seem to get no responses?!
I found this paper that was useful to me :
http://people.bath.ac.uk/enscjb/airtex.pdf
It mentions the figure 2.0 - 2.6 L/min/kW. Is this kW, the bhp?
Question 1:For a Nissan Maxima (3.5 L engine), could I take this number as 2.4?
--------------------------------------
To get the mass flow rate I would have to multiply by the density of the coolant. Now I couldn't find the density of the coolant as a function of temperature. But I did find the specific gravity as a function of temperature:

Question 2: For density, do I multiply the specific gravity with the density of water at 4 degrees C or do I multiply it with the density of water at the given temperature?
Also,
Question 3: Since there is a temperature gradient across the radiator, which temperature do I consider while calculating the fluid properties hot_side temperature, or cold_side temperature or the mean?
