Question details

This one is giving me trouble.

4 (20pts) A transistor with a height of 0.4 cm and a diameter of 0.65 cm is mounted on a circuit board. The transistor is cooled by air flowing over it with an average heat transfer coefficient of 30 W/m 2 K. If the air temperature is 50°C and the transistor case temperature is not to exceed 70°C, the amount of power this transistor can disielyDiscard any heat transfer rom the transistor base. Air 50°C Power transistor 0,65cm T, S 70°C 0.4 cm-

Any help is greatly appreciated.

Thanks.
