| Abstract: | A corrected method of determining hull form factor 1+K is presented. Thefoundation is also derived from the assumption given by Hughes and Prohaska,but the solution of1+K can be obtained from the analytical relation between coefficients of total and of viscous-pressure resistance. In comparison with Prohaska's method the value of hull from factor isstationary and reasonable as applying all of information for resistance test results to thecomputatlon. |
