Variables Used
Total Longitudinal Current Load on a Vessel - (Measured in Newton) - Total longitudinal current load on a vessel [Force] is the summation of form drag of a vessel, skin friction and the vessel propeller drag.
Form Drag of a Vessel - (Measured in Newton) - Form Drag of a Vessel [Force] is increase in resistance due to pressure.
Skin Friction of a Vessel - Skin Friction of a Vessel is defined as the friction at the surface of a solid and a fluid in relative motion.
Vessel Propeller Drag - (Measured in Newton) - Vessel Propeller Drag [Force]. The incremental drag due to slipstream of running propeller is shown to decrease with air speed and increase with propeller pitch angles.
