1 dzień temu · This review explores a variety of techniques that utilize air injections beneath a vessel’s hull to reduce drag and consequently improve energy efficiency. It focuses on the methodologies of microbubble drag reduction (MBDR), air layer drag reduction (ALDR), and air cavity drag reduction (ACDR), offering insights into their design, operational mechanisms, and potential applications. This ...
1 dzień temu · The Boat Speed Calculator, powered by Crouch's formula, is a tool designed for enthusiasts and professionals in marine design and navigation. It assesses the potential top speed of boats of various types by considering their power, displacement, and a unique factor known as the Crouch constant.
4 dni temu · Measurement of volume by displacement, (a) before and (b) after an object has been submerged. The amount by which the liquid rises in the cylinder (∆V) is equal to the volume of the object. The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape.
20 godz. temu · Determine the weight of the ship in seawater. The displacement of the ship is given as 24,000 tons. Since 1 marine ton is equivalent to 1,000 kg, the weight of the ship in kilograms is: \[ 24,000 \text{ tons} \times 1,000 \text{ kg/ton} = 24,000,000 \text{ kg} \] Step 2/10 Convert the weight of the ship to a force in kilonewtons (kN).
