Question

Radial aluminum blades are added to a small compressor as shown in the figure. There is a heat transfer rate of 1 kW between the vane compressor and the surrounding air at 20 C. Each blade is 100 mm long, 30 mm high and 5 mm thick. Calculate the required number of blades so that the temperature at the place where the blade is attached to the surface does not exceed 120C, with the task that h = 15 W / m2K for the perimeter.
