Determine the heat-transfer rate from an electronic chip whose surface temperature

Determine the heat-transfer rate from an electronic chip whose surface temperature is 33C and has an exposed surface area of 5cm2. The temperature of the surrounding air is 20C. The heat-transfer coefficient for this situation is h=25m2KW. Express your answer in both SI units (in W) and U.S. Customary units (in Btu/h). rate in W W rate in Btu/h Btu/h What is the R-factor (film resistance, in Km2/W ) for this situation? km2/W
