A constant heat flux comes to the x = 0 surface of a plane wall with a thickness of 25 cm and a heat transfer coefficient of 15 W / mK. The plane wall loses heat from the x = L surface by both convection and radiation. The temperature of the x = L surface is 45 ° C, the spreading rate is 0.8, and this surface is exposed to 20 ° C temperature and 15 W / m2K heat convection conditions. Since the temperature of the surfaces surrounding the plane wall is 16 ° C, determine the temperature of the x = 0 surface of the wall.
