241.55 / 36.00 = 6.71 36.00 / 9.33 = 3.85 9.33 / 15.00 = 0.62 241.55 / 15.00 = 16.10 44,900 / (241.55 x 36.00 x 9.33) = 0.55 4.00 meters at 47,200 mt |
1) At 1938 values.
2) This is the height of the hull sides measured amidships from the upper deck to the bottom of the keel.
3) The block coefficient (CB) is the ratio of the underwater hull volume of a ship at a particular draft to the volume of a rectangular prism (the circumscribing prism) of the same length, breadth, and draught as the ship.
CB = V/(L x B x T)
4) The midship section coefficient (CM) is the ratio of the area of the underwater midship section (Am) of a ship at a particular draft to the area of a rectangle (the circumscribing rectangle) of the same breadth and draught as the ship.
CM = Am/(B x T)
5) The waterplane coefficient (CWP) is the ratio of the area of a ship’s waterplane (AWP) to the area of a rectangle (the circumscribing rectangle) of the same length and breadth as the ship. CWP = AWP/(L x B)
6) The longitudinal prismatic coefficient (CP) is the ratio of the underwater hull volume of a ship to the volume of a prism with length equal to the ship’s and cross-section area identical to the midship section. In other words, the prismatic coefficient is equal to the block coefficient (CB) divided by the midship section coefficient (CM).
CP = V/(Am x L) = CB/CM
Bismarck block coefficient is calculated as follows: CB = 44,900 mt / (241.55 m x 36 m x 9.33 m) = 0.55
Bismarck midship section coefficient is calculated as follows: CM = 326 m² / (36 m x 9.33 m) = 0.97
Bismarck waterplane coefficient is calculated as follows: CWP = 5,740 m² / (241.55 m x 36 m) = 0.66
Bismarck prismatic coefficient is calculated as follows: CP = 0.553 / 0.97 = 0.57
