Consider mass loss from a smooth wet flat plate due to forced convection at atmospheric pressure. The plate is \(0.4 \mathrm{~m}\) long and \(2 \mathrm{~m}\) wide. Dry air at \(300 \mathrm{~K}\) and a free stream velocity of \(3.5 \mathrm{~m} / \mathrm{s}\) flows over the surface, which is also at a temperature of \(300 \mathrm{~K}\). Estimate the average mass transfer coefficient \(\bar{h}_{m}\) and determine the water vapor mass loss rate \((\mathrm{kg} / \mathrm{s})\) from the plate.
