In Problem 11.3, repeat the solution of part (b), this time accounting for evaporation at the free surface of the hot water. The relative humidity of air is 30%. For simplicity, neglect the contribution of mass diffusion to natural convection at the water surface and assume that heat transfer at the water surface is gas-side controlled.
