Saturated steam at 0.2 bar condenses with a convection coefficient of \(6000 \mathrm{~W} / \mathrm{m}^{2} \cdot \mathrm{K}\) on the outside of a brass tube having inner and outer diameters of 16 and \(19 \mathrm{~mm}\), respectively. The convection coefficient for water flowing inside the tube is \(5000 \mathrm{~W} / \mathrm{m}^{2} \cdot \mathrm{K}\). Estimate the steam condensation rate per unit length of the tube when the mean water temperature is \(30^{\circ} \mathrm{C}\).
