Question
motor body is 360 mm in diameter (outside) and 240 mm long. Its surface
temperature should not exceed 55 °C when dissipating 340W. Longitudinal fins of 15 mm
thickness and 40 mm height are proposed. The convection coefficient is 40W/m2 °C.
determine the number of fins required. Atmospheric temperature is 30°C. Thermal
conductivity = 40 W/m°C. Hint: q = vkAhP Ob tanh (mL), P=2L , A=Lt.
