Derive an expression for the temperature distribution in an infinitely long rod of uniform cross section within which there is uniform heat generation at the rate of 1 W/m. Assume that the rod is attached to a surface at Ts and is exposed through a convective heat transfer coefficient h to a fluid at Tf.
GIVEN
• An infinitely long rod with internal heat generation
• Temperature at one end = Ts
• Heat generation rate ( q
GA) = 1 W/m
• Convective heat transfer coefficient = hc
• Ambient fluid temperature = Tf
FIND
• Expression for the temperature distribution
ASSUMPTIONS
• The rod is in steady state
• The thermal conductivity (k) is constant
