The external wall of a room in a house has a cross-sectional area of 34.13 m2. The convective heat transfer coefficients for the inside air are 8.77 Wm-2 0C-1. It is desired for the room to have a temperature of 23.740C and the external temperature to be 0 0C. The heater in the room is capable of supplying heat at a steady rate of 934 W.

Find the temperature for the internal surface of the wall, in 0C, giving your answer to 3 decimal places.
