Just divide a boat's sail area in square feet by its wetted surface area in square feet (SA/WS = SA ÷ WS),

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
reduction ratio= initial cross sectional area/final cross sectional area
How to calculate the ratio of the inlet-to-exit area of the nozzle
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
1. Calculate the surface area 2. Calculate the volume 3. Divide
FAR=Total floor area of building / Total lot area
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
the p/a ratio is the sum of the perimeter divided by the area therefore if perimeter is 20m and the area 25m2 the sum is 20/25=0.8
You calculate the areas of two shapes and then divide one area by the other to find the ratio of their areas.
