Suppose the rod in Problem 2-128 is very long. What would the zero-voltage heat transfer be in this case?
Problem 2-128
A stainless-steel rod having a length of 10 cm and diameter of 2 mm has a resistivity of 70 μΩ ∙ cm and thermal conductivity of 16 W/m ∙ ºC. The rod is exposed to a convection environment with h = 100 W/m2 ∙ ºC and T = 20ºC. Both ends of the rod are maintained at T = 100ºC. What voltage must be impressed on the rod to dissipate twice as much heat to the surroundings as in a zero-voltage condition?
