Heat Transfer Coeff on the water air interface
 
Dear All,

I am looking for a value for the heat transfer coefficient between water and air.

The air is at room temperature and is supposed not to change it's temperature, and water being cooled from 40 to 10 degrees centigrade.

Under this condition, what's this coefficient's value?

Thanks in advance, A

How fast is the air moving over the water?

it is still. the water's maximal velocity is 1-10 centimeters per second.

hello
 
why not compute it via the sofeware ,now i am doing the research on how to simulation the convection heat transfer coefficient via ansys.
i am a student in china .my email is shaoyunsjj@hotmail.com,i want to make friends with you.it's so kind of you to send me a letter.thank you !
i am really happy that i can express my thought in american CFD forum.it's a perfect to improve my level.
