made at 10 knots. For some runs (particularly at Station VI in the separated flow zone aft of 

 the lip of the overboard discharge) a negative manometer deflection occurred. Such readings 

 are entered in Table 1 as **. 



The average temperatures prevailing during the tests were: 



a. sea water temperature, 78°F; and 



b. manometer board temperature, 103°F. 

 Using these conditions: 



u = k X 1.871 y/Kh for the tetrabromethane manometers 

 and 



u = k X 4.792 yfKh for the mercury manometers, 

 where AA is the manometer reading in inches and u is the velocity in knots. 



The ship speed calibration was obtained by measuring revolutions over the trial course 

 just prior to the boundary-layer survey runs. Speeds given for individual runs are probably 

 accurate within ± 0.10 knot.
