A power transistor with three 0.8 mm diameter leads of a copper-silver alloy (k = 400 W/m-K) dissipates 3.5 Watts of
power. The printed circuit board (PCB) on which the transistor is mounted is maintained at 30 C. The air temperature is
20 C and the heat transfer coefficient for the leads is 60 W/m² K. The length of the leads from the transistor to printed
circuit board is 9.0 mm.

A window in a tall building experiences a horizontal wind flow parallel to the surface at a velocity of 8 m/s. The window
measures 2 m high, 1.5 m wide and 6.5 mm thick. The transition from the building wall to the window glass surface is
not smooth. The window casement that surrounds the edge of glass pane is raised 10 mm above the surface of the glass
and adjacent wall structure. Inside the building, the air temperature and heat transfer coefficient for the interior surface
are 21 °C and 9 W/m² K respectively. The window has a uniform thermal conductivity of 1.4 W/m K. If the outdoor air
temperature is 5 °C, determine the rate of convective heat loss from the window. Develop a thermal resistance network
for the window system. Please state and justify all assumptions. Neglect any conduction through the casement.
Assume the following air properties: kair =0.0248 W/m K, v= 14.20 x 106 m²/s, Pr = 0.712.
