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 รท 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.
There's no firm relationship between the magnitudes of distance and displacement, except that displacement can never be greater than distance. So if you're looking for a ratio, I guess (distance)/(displacement) = or > 1
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.
There isn't a set displacement to horsepower ratio - hence, horsepower can't be determined by displacement alone.
how does the area of the sail affect how a model boat sail
Displacement: The weight of the water the boat displaces. Hull weight: The weight of the hull of the boat
1 is to 1
12:3
It's not always the same number. But whatever that ratio happens to be in a specific situation, it can never be less than ' 1 '.
Perimeter ratio is: is a path that surrounds an area and area ratio is: Area ratio is the cross sectional area of the nozzle exit divided by the cross sectional area of the nozzle throat.
