Question: Hot water flows through pipes that are embedded in a concrete slab. A section of the slab is shown in the accompanying figure. The temperature of the water inside the pipe is 50°C.with a corresponding heat transfer coefficient of 200 W/m • K. With the conditions shown at the surface. use ANSYS to determine the temperature of the surface. Assuming that the heat transfer coefficient associated with the hot-water flow remains constant. find the water temperature at which the surface freezes. Neglect the thermal resistance through the pipe walls.
