RESISTANCE AND POWERING OF SHIPS. Define effective horsepower (EHP) conceptually and mathematically. State the relationship between velocity and total resistance, and velocity and effective horsepower. Write an equation for total hull resistance as a sum of viscous resistance, wave making resistance and correlation resistance.
Understanding and calculating marine displacement is essential for the design and operation of ships. This tutorial delves into the formulas and calculations associated with marine displacement, focusing on length, breadth, draft, and block coefficient.
12 lip 2020 · Velocity Ratio lets us know if the displacement of load is equal to or more or less than the displacement of effort. Velocity Ratio Formula. The velocity Ratio Formula is represented by 2 equations listed below. 1) Velocity Ratio = velocity of the effort / the velocity of the load = V E / V L ……
(B) describe and analyze motion in one dimension using equations with the concepts of distance, displacement, speed, average velocity, instantaneous velocity, and acceleration; (F) identify and describe motion relative to different frames of reference.
Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well.
Given a boat velocity of 4 m/s, East and a river velocity of 3 m/s, North, the resultant velocity of the boat will be 5 m/s at 36.9 degrees. Motorboat problems such as these are typically accompanied by three separate questions: What is the resultant velocity (both magnitude and direction) of the boat?
For a displacement boat, speed is a function of waterline length. The maximum theoretical speed is ordinarily assumed to be 1.34 times the square root of the LWL.
