Hydrodynamic Resistance
Hydrodynamic resistance is the force that opposes the motion of a ship through water. It is caused by the frictional resistance of the water against the hull of the ship and the wave-making resistance created by the movement of the ship through the water. Hydrodynamic resistance is affected by the shape and size of the ship's hull, the speed of the ship, and the properties of the water, such as viscosity and density. Reducing hydrodynamic resistance is important for improving the efficiency and speed of a ship, and can be achieved through design modifications, such as optimizing the hull shape and adding features like bulbous bows and stern flaps.
