cooling information

[foza_11]

i have compact heat exchangers by kays and london
i have some problems in my first iteration , can any one provide me with the mass flow rates of air and water is them 0.45 and 0.15 kg/sec.
also,the water side surface geomtery as haydrulic diameter , rato between free flow area andfrontal area ,ratio of total heat transfer area on one fluid side of an exchanger to the total volume of an exchanger , please provide me with this information i have dead line for calculation tommorow but i doesn't have the radiator .
thanks for help all.

Water, like other liquids, fills the geometry of the container which holds it.

i don't mean the physical properties, i mean the geometrical properties :no. of tubes ,the no. of passes per tube ,ratio between free flow area andfrontal area ,ratio of total heat transfer area on one fluid side of an exchanger to the total volume of an exchange,tube width and high .
i wish find this few information to complete my first iteration .

You could get a radiator, and count the tubes.

thanks for your irony suggestion :!

You could find a picture of the radiator. Or go count the tubes in the radiator for a small car.
