The primary formula used to calculate the displacement of a ship is based on its physical dimensions and block coefficient. The block coefficient is a dimensionless number that describes how closely the shape of a ship resembles a rectangular block. Displacement = Length × Breadth × Draft × Block Coefficient. Where:
Define position, displacement, distance, and distance traveled. Explain the relationship between position and displacement. Distinguish between displacement and distance traveled. Calculate displacement and distance given initial position, final position, and the path between the two.
27 wrz 2022 · A boat, which is traveling more slowly than a river, must cross the river. Calculate the angle of the boat that will minimize the downstream displacement of...
a) Use dimensional analysis to find a proportional relationship between the speed of the boat v boat in terms of the quantities: length l of the boat, the density ρ of the water, and the gravitational acceleration g. Hint: You may not need all these quantities and you can write v boat ∼lxρygz, (0.1) where you should find the values of x,y,and z
Calculation. Shipboard stability computer programs can be used to calculate a vessel's displacement. The process of determining a vessel's displacement begins with measuring its draft. [3] . This is accomplished by means of its "draft marks".
• Bow: The front or forward part of the boat. • Displacement: The weight of the water displaced by the boat. We’ll discuss what “water displacement” means in the “Buoyancy” section later in the chapter. • Draft: The depth of the boat below the waterline. Also used to describe the depth of water necessary to float a boat.
