Web8 jun. 2024 · The frictional resistance of the ship’s hull is calculated from the basic formula for resistance which the ship’s hull surface experiences by moving against a viscous fluid (water): Resistance = Resistance Coefficient x pressure x Surface Area. Pressure = ½ ρV 2. Surface area = wetted surface area of the vessel.
