FURTHER INVESTIGATIONS ON COMPONENTS OF SHIP RESISTANCE

The accomplishments during the eleventh year of research on components of ship resistance, supplementing that reported in IIHR Report No. 162 on the first 10 years, are summarized. These include the derivation of a more exact formula for calculating the viscous drag of a ship model from wake-survey measurements, a refinement of a procedure for determining wave resistance from surface-profile measurements, studies of the effect of the wake on wave-resistance measurements, and some contributions to the problem of correcting resistance measurements for the influence of tank boundaries.
