SA/D Ratio is the sail area/displacement ratio. This ratio indicates how fast the boat is in light wind. The higher the number the faster the boat.
* Cruising Boats have ratios between 10 and 15.
* Cruiser-Racers have ratios between 16-20.
* Racers have ratios above 20.
* High-Performance Racers have ratios above 24.
SA / D = Sail Area / (Displacement in Cubic Feet )2/3
Just divide a boat's sail area in square feet by its wetted surface area in square feet (SA/WS = SA ÷ WS),
A D/L ratio is calculated by dividing a boat's displacement in long tons (2,240 pounds) by one one-hundredth of the waterline length (in feet) cubed.
The ratio is 1.
The modulus of the ratio of distance to displacement is always less than or equal to 1, as displacement is the shortest distance between two points. The unit for this ratio is dimensionless, as it is a pure number without units.
These have to do with the hydraulic density. In automobile, the density increases therefore making the hydraulic ratio to displace more than any hydraulic ratio in a displacement.
The ratio of distance to displacement is always equal to or greater than 1. This is because distance will always be equal to or greater than displacement, as distance is the total length of the path traveled while displacement is the difference between the final and initial positions.
how does the area of the sail affect how a model boat sail
The ratio of an object's displacement to the interval during which the displacement occurred gives you the object's average velocity. It is calculated by dividing the displacement by the time interval. Average velocity is a vector quantity that indicates both speed and direction of the object's motion.
The ratio of the magnitudes of distance and displacement is always equal to or greater than 1. This is because distance is a scalar quantity that represents the total length of the path traveled, while displacement is a vector quantity that represents the straight-line distance between the initial and final positions.
The numerical ratio of displacement to distance for a moving object is 1 when the object moves in a straight line in a single direction. This means that the displacement is equal to the distance traveled. If the object moves in a more complex path, the ratio may vary depending on the trajectory.
There isn't a set displacement to horsepower ratio - hence, horsepower can't be determined by displacement alone.
Displacement: The weight of the water the boat displaces. Hull weight: The weight of the hull of the boat
