1 dzień temu · Calculation Formula. The core of the Boat Speed Calculator lies in Crouch's formula: \[ S = \sqrt{\frac{P}{D}} \times C \] where: \(S\) represents the boat's top speed in miles per hour, \(P\) is the power supplied to the boat in horsepower, \(D\) is the displacement of the boat in pounds, \(C\) is the Crouch constant, specific to the boat's type.
3 dni temu · This useful calculator computes an estimate of boat speed for a modern planing monohull using inputs of the power at the propeller shaft, the total boat weight, and a coefficient called the hull factor.
5 dni temu · The Displacement to Length Ratio (DLR) is a crucial measure in naval architecture, indicating how heavy a boat is relative to its waterline length. This ratio is used to estimate the boat's performance, including its speed, stability, and sea-keeping abilities.

4 dni temu · Archimedes’ principle, physical law of buoyancy stating that any body submerged in fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body. Learn more in this article.
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 ...
5 dni temu · The displacement of a submarine can be approximated using a simplified formula: \[ \text{Displacement (tons)} = 0.1 \times \text{Length (m)} \times \text{Beam (m)} \times \text{Draft (m)} \] This formula provides a rough estimate and is based on the submarine's dimensions.
