Water at a temperature of 77°C is to be evaporated

slowly in a vessel. The water is in a low-pressure container surrounded by steam as shown in the sketch

below. The steam is condensing at 107°C. The overall

heat transfer coefficient between the water and the steam

is 1100 W/m2 K. Calculate the surface area of the container that would be required to evaporate water at a rate

of 0.01 kg/s.
