Nothing as easy from basic principles as for conduction or radiation.
You can multiple the mean heat carried by the convecting liquid by it's mass rate of flow
Δ T = c p ( T i n T o u t ) Δ V Δ t ρ Δ t .
Where T i n is the mean temperature of the liquid moving toward the sink (cool side) and T o u t is the temperature of the liquid moving the other way.
The problem is that you can't get the temperature(s) of the convecting liquid or the flow rate without detailed calculations or measurements.
For the generaly case you pretty much have to go to CFD.
