In industrial heat exchanger design, the overall heat transfer coefficient U is estimated from the equation 1/U = 1/hi + 1/ho, where hi and ho are the convective heat transfer coefficients on the inner and outer side of the tube, respectively. This is valid for (i) tube of (ii) thermal conductivity.
