[tex] Q = \frac{T_{steam}-T_{water}}{\frac{1}{Ah_{water}}\frac{d}{Ak_{wall}}\frac{1}{Ah_{steam}}} = L\dot{m}

[/tex]

where L is the latent heat released by the condensing steam. The trouble is, I don't know the convective heat transfer coefficients. Is there a way to calculate the h-coefficients based on flow velocity or what's the deal with them?
