Summary:

The coefficients found in this research vary with Reynolds number and are high as compared with those of Eiffel.

The curve resulting from the summation of the coefficients for four cups agrees with the static torque curve of a Robinson type cup anemometer.

The effect of interference upon a single cup is to increase the drag and normal force coefficients.

This thesis presents the results of an investigation wherein the change of the normal force coefficient with Reynolds number was obtained statically for a 15.5-centimeter hemispherical cup under the following conditions : (1) Single cup with no interference (2) Single cup with three-cup interference (3) Four cups.
