WebTherefore, the EEXI calculation guideline offers the option to calculate the reference speed using an approximate formula for the ship type and installed power. With an included … WebThe speed of the ship (axial speed of the prototype propeller) is v1 = 9.774 m/s (= 19 knot). The following variables are relevant: We have six variables and three dimensions, therefore there are 6 − 3 = 3 dimensionless variables. The Dimensional Set is yielding (a) Therefore the Model Law is (b) where SF is the Thrust Scale Factor
