Two surfaces of a long L-shape object are maintained at
temperatures Ts1 (along the x-axis) and Ts2 (along the
y-axis) as shown in the figure. All other surfaces are exposed to a convection
boundary (Tf and h). Use the method described in Section 3 of
Chapter VII to find temperatures at location 1, 5, and 7. Data: a = 2 cm, Ts1
= 50 C, Ts2 = 100 C, Tf = 15 C, h = 10 W/m2
