NOTE ON AN ACCURATE TURBULENT VELOCITY PROFILE FOR USE AT SHIP SCALE

Determinations of von Karman's constant and of B sub o, the constant in the law of the smooth wall, are compared and the considerable disagreement is explained. One determination, however, unique in its nature, seems definitive. A turbulent velocity profile equation with revised constants and a modified wake term is fitted with high precision to measurements R sub n = 10 to the 7th power. Calculations that employ the profile lead to planar drag coefficients about 5 percent larger at full scale than those predicted by the 1957 International Towing Tank Conference (ITTC) line.
