Saturated steam at atmospheric pressure and 100\deg C condenses on a vertical plate of 1 m height and 0.2 m width. The surface temperature of the plate is maintained at 80\deg C. Calculate (1) the condensing heat transfer coefficient at 0.3 m (ii) the film thickness at 0.3 m from top (iii) average heat transfer coefficient and (iv) rate of steam condensation. Assume laminar flow.
