Excerpt from Steamship Coefficients, Speeds and Powers: Containing the Dimensions and Performances of Vessels and Many Progressive Trials of Ships and Models; With Notes on Froude's Law of Comparison, Skin Friction Correction, Engine Efficiency, the Admiralty "Constant" System of Notation, Taylor's Methods, Th The Law Of Comparison has already been partly stated It is sometimes described as the Theory Of Mechanical Similitude, or Fronde's extended Law of Comparison. The principle of Similitude, first enunciated by Sir Isaac Newton, and proved last century by French mathematicians, M. Reech and others, will be found deduced mathematically by rear-admiral D. W. Taylor, in his Speed and Power of Ships, the book which contains the well-known and widely used curves of residuary resistance per ton of displacement. The corresponding speeds for Similar ships are Speeds pro portional to the square roots of their linear dimensions. The corresponding displacements of similar ships are displace ments proportional to the cubes of their linear dimensions. The corresponding residuary resistances for similar ships at similar speeds are resistances proportional to the cubes of their linear dimensions.
