ENGI 5602: Process Heat Transfer Winter 2019 Assignment 2 Due Date: February 11, 2019 Problem 01: a) Calculate the steady state heat transfer rate through the composite wall in W /m2 [10 pts). b) Find T2 in K [10 pts). L-0.2 m -0.03 m 7, = 1250 K T2 ? = 310 K T2 20.07 W/m.K Ts
L2 -0.03m T1 = 1250 K T2 7 T5 = 310 K k, = 1.0 W/m·K kz= 0.07 W/m·K T2 k1 k2 T. Problem 02: Find analytical expression for the temperature distribution T(x) in the plane wall which has uniform surface temperatures T1 (x = 0) and T2(x = L) and Ti > T2-Thermal conductivity varies linearly with temperature, i.e. kko(1 + bT). Consider three different cases, (i) b >0, (ii) b 0, and (ii) b <0. For each case, which one is the closest T (x) profile in Figure below? [15 pts] T2
