WebCalculate the total frictional resistance of a yacht: hull, keel, and rudder. The frictional resistance is a force that is generated when the underwater parts of the boat and the water around are in relative movement. It is a hydrodynamic force, and as a resistance, it works in the opposite direction to the movement, trying to slow the boat down. convert pdf till wordhttp://oilfieldwiki.com/wiki/Wave_making_resistance convert pdf to 10 kbWebApr 17, 2006 · RE : Wave Making resistance: ( Please Correct me if I am wrong) Yes viscous pressure resistance and wave making resistance are different but in CFX when you calculate the pressure resistance it combines both the wave making and viscous pressure resistances.
