The rate of heat flow per unit length q/L through a hollow cylinder of inside radius ri and outside radius ro is q/L=(AkT)/(rori) where A=2/(rori)/ln(ro/ri). Determine the percent error in the rate of heat flow if the arithmetic mean area (ro+ri) is used instead of the logarithmic mean area A for ratios of outside-to-inside diameters (Do/Dj) of 1.5, 2.0, and 3.0. Plot the results.

There is a piston-cylinder assembly with a mass of 50 kg and a surface area of 0.01 m2. The mass of air is 5 g. The initial volume of air is 5 liters. Atmospheric pressure is 100 kPa. As the specific internal energy of the air decreases by 260 kJ/kg the volume of air is also gradually decreasing to 0.002 m3. Ignore friction that is between the piston and the cylinder surface. Determine the heat transfer to the air. (kJ)
