76. All surfaces of an infinitely lang heating element, having a cross section in the shape of a cross, are maintained at 300 C. Due to symmetry, only a quarter of the cross section is shown in the figure Heat is uniformly produced in the element at a rate of 100 kW/m. Find the temperature distribution in the element at the locations shown in the figure. The element thermal conductivity is 35 W/m K. All surfaces are exposed to a convection boundary condition of T; = 40 C and h = 1200 W/m^2c.

76. All surfaces of an infinitely lang heating element, having a cross section in the shape of a cross,
are maintained at 300 C. Due to symmetry, only a quarter of the cross section is shown in the figure.
Heat is uniformly produced in the element at a rate of 100 kW/m. Find the temperature distribution
in the element at the locations shown in the figure. The element thermal conductivity is 35 W/m K.
All surfaces are exposed to a convection boundary condition of T; = 40 C and h = 1200 W/m^2c.
