Steady-state temperatures at selected nodal points of the symmetrical section of a flow channel are known to be T2=125C,T3= 162.7C,T5=101.3C,T6=97.22C,T8=117.8C, and T10=102.2C. The wall experiences uniform volumetric heat generation of q=1.6106W/m3 and has a thermal conductivity of k=10W/mK. The inner and outer surfaces of the channel experience convection with fluid temperatures of Tmj=50C and Tm,0=25C and convection coefficients of hl=500W/m2K and h0=250W/m2K.
