Hi guys can anyone help(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem trying to find an equation to work out the heat rejection for a car radiator I have

Heat exchange = u x a x deltaT

But I cannot find u ?

The radiators have flat profile tubes and wave fin they are made from aluminium, the formulae would have to take this into consideration and work at various mass flows through both the airside. And waterside these would be affected by vehicle speed ie the force of air pushed through the radiator. Can anyone help as I have been looking at this for hours and not getting anywhere.

Please help

Cheers
