Steam condenses at 100°C on the outer surface of a pipe with a thermal conductivity of 180 J/ms°C. The surface heat transfer coefficient of the water flowing in the pipe is 4000 J/m²s°C, and the heat transfer coefficient created by the steam condensing outside is 10000 J/m²s°C. The length of the pipe is 5 m and the thread diameter is 25 mm. Since the pipe thickness is 1 mm, calculate the total heat transfer coefficient and the rate of heat transfer from the condensed steam to the water at 15 °C
