Atransistor with a height of 0.4 cm and a diameter of 0.6 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/m2 ·k. if the air temperature is 55°c and the transistor case temperature is not to exceed 70°c, determine the amount of power this transistor can dissipate safely. disregard any heat transfer from the transistor base.
