The steady state temperature t1 is prescribed, node 3 is insulated, there is no heat load, and heat is transferred across the entire length of the body by convection. Recall that the flux due to convection is qconv = h(ta -t). K, = 40w/mk, the convection coefficient h = 300w/m2k, l = 1m, the cross-sectional area is 1m2 and the perimeter of the cross section is 1m2. Determine t2 and t3 in terms of t1 and ta. State why you think your answer is correct or incorrect. t.
