CHAP 5 Finite Elements for Heat Transfer Problems 291 9. A well-mixed fluid is heated by a long iron plate of conductivity k = 12 W/m/ o C and thickness t = 0.12m. Heat is generated uniformly in the plate at the rate Q g = 5,000 W/m 3 . If the surface convection coefficient h = 7 W/m 2 / o C and fluid temperature is T f = 45 o C, determine the temperature at the center of the plate T c and the heat flow rate to the fluid q using three one-dimensional elements. Solution: Assuming that the plate is wide enough, we model the problem with 1D elements of unit area. Using L ( e ) = 0.04 m for all the three elements., the element matrix equations become Element 1: (1) 1 1 (1) 2 2 1 1 1,000 300 1 1 1,000 T q T q       Element 2: (2) 2 2 (2) 3 3 1 1 1,000 300 1 1 1,000 T q T q  
