We have a wall (k = 10 W/mK) with a thickness of 0.4 m. At a certain instance of time temperature distribution is given by T(x) = 50 x²– 450 x + 350. - Please calculate the rate of heat transfers entering and leaving the wall for a unit surface area and also find the change in the energy storage of the wall. - If the environment temperature is 85 °C, what is the convection coefficient between the cold surface of the wall and environment.
