Variables Used
Skin Friction Coefficient - Skin Friction Coefficient refers to the dimensionless parameter that quantifies the resistance between the surface of a structure and the surrounding soil or water.
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.
Water Density - (Measured in Kilogram per Cubic Meter) - Water Density is mass per unit volume of water.
Wetted Surface Area - (Measured in Square Meter) - Wetted Surface Area is the total area of outer surface in contact with the surrounding water.
Average Current Speed for Skin Friction - (Measured in Meter per Second) - Average Current Speed for Skin Friction or calculating skin friction (or frictional resistance) on a vessel's hull, can vary widely depending on the type of vessel and its operational environment.
Angle of the Current - Angle of the Current refers to the direction at which ocean currents or tidal flows approach a coastline or a coastal structure, relative to a defined reference direction.
