A cast iron tank 25 mm thick contains a solution which is kept to boil at 95°C. The outer surface of the tank is maintained at {T}°C, while the inside of the tank is covered with a layer of enamel 1 mm thick (k = 0.86 W/mK). The heat transfer coefficient for the boiling solution is 4.5 kW/m²K. Calculate the overall heat transfer coefficient. Use k = 50 W/mK for cast iron. Write your answer to 2 decimal places.
