Page 328 - Computation of Augmented Surface. — To compute the exact augmented surface of a vessel of any ordinary shape would be a problem of impracticable labour and complexity. The method employed, therefore, as an approximation for practical purposes, is to choose in the first instance a figure approximating to the actual figure, but of such a kind that its augmented surface can be calculated by a simple and easy process, and to use that augmented surface instead of the exact augmented surface of the ship...
Page 322 - The conclusion to be drawn from these principles is, that for each vessel there is a certain limit of speed, below which the resistance due to the production of waves is insensible ; and that as soon as that limit is exceeded, that resistance begins to act, and increases at a very rapid rate with the excess of speed Through the discoveries of Mr. Scott Russell, a vessel can be designed in which this kind of resistance shall -bo insensible up to a given limit of speed; and therefore the resistance...
Page 323 - Ibs. per cubic foot for sea-water). V. A factor called the coefficient of friction, depending on the material with which the ship's skin is coated, and its condition as to roughness or smoothness. The sum of the products of the Factors I. and II. for the whole skin of the ship has of late been called her AUGMENTED SURFACE ; and the Eddy-resistance of the whole ship may therefore be expressed as the product of her Augmented Surface by the Factors III. IV. and V. above mentioned...
Page 328 - ... that its augmented surface can be calculated by a simple and easy process, and to use that augmented surface instead of the exact augmented surface of the ship ; care being taken to ascertain by comparison with experiments on ships of various sizes and forms, whether the approximation so obtained is sufficiently accurate.
Page 323 - ... pressure at the bow and diminution of the pressure at the stern. The existence of this kind of resistance has been recognised from an early period. Beaufoy made experiments on models to determine its amount ; Mr. Hawksley and Mr. Phipps have included it in a formula for the resistance of ships ; and...
