A plane wall, with a surface area of 30 m2 and a thickness of 20 cm, separates a hot fluid at a temperature of 170 ?C from a cold fluid at 15 ?C. Under steady-state conditions, the temperature distribution across the wall is given by T = 150 -600x -50×2 where x is the distance measured from the hot wall in meters and T is the temperature in degrees Celsius. If the thermal conductivity of the wall is 10 W/m·K: a) Calculate the average heat transfer coefficients at the hot and cold surfaces. b) Determine the rate of energy generation within the wall.
