Studies on water movements and sediments in Southern Lake Michigan : part 1[-3] ... / by John C. Ayers.

III and IV both moved at apparent mean speeds of 0.34 mph. If the difference in indicated speeds is taken to be the result of windage on the drogue float, then the windage errors are 0.05/0.29 or 17.5%. Test of 26 October 1963 (, OldF Drags)o In this test drogue II again carried two current drags in tandem and was compared to drogue III, a surface drogue. Drogue II travelled at an indicated speed of 0.43 mph; drogue III moved at an indicated speed of 0.52 mpho Again taking the difference in indicated speeds as a measure of the towing effect of wind pressure on the drogue float, we have 0.09/0.43 or 20.9% windage error. NOTE The indicated speeds of drogues that are given in the preceding sections have not been corrected in any way for windage error. 41
