PROBLEM 4.41 K NOWN: Two-dimensional grid for a system with no internal volumetric generation. FIND: Expression for heat rate per unit length normal to page crossing the isothermal oundary. b SCHEMATIC: ASSUMPTIONS: (1) Steady-state conditions, (2) Two-dimensional heat transfer, (3) onstant properties. C ANALYSIS: Identify the surface nodes (T s ) and draw control volumes about these nodes. Since there is no heat transfer in the direction parallel to the isothermal surfaces, the heat rate ut of the constant temperature surface boundary is o abcdef q qqqqqq ′′′′′ =+++++
