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.

why not compute it via the sofeware ,now i am doing the research on how to simulation the convection heat transfer coefficient via ansys.
