PROBLEM 2.10 KNOWN: Temperature distribution in solid cylinder and convection coefficient at cylinder surface. FIND: Expressions for heat rate at cylinder surface and fluid temperature. SCHEMATIC: ASSUMPTIONS: (1) One-dimensional, radial conduction, (2) Steady-state conditions, (3) Constant properties. ANALYSIS: The heat rate from Fourier’s law for the radial (cylindrical) system has the form q kA dT dr rr = . Substituting for the temperature distribution, T(r) = a + br
