Vessel Draft given Form Drag of Vessel Solution

Follow our step by step solution on how to calculate Vessel Draft given Form Drag of Vessel?

FIRST Step Consider the formula

T = \frac{F c, form}{0.5 \cdot ρ water \cdot C c, form \cdot B \cdot {V c}^{2} \cdot \cos (θ c)}

Next Step Substitute values of Variables

∴

T = \frac{0.15kN}{0.5 \cdot 1000kg/m³ \cdot 5 \cdot 2m \cdot {728.2461m/h}^{2} \cdot \cos (1.15)}

Next Step Convert Units

∴

T = \frac{150N}{0.5 \cdot 1000kg/m³ \cdot 5 \cdot 2m \cdot {0.2023m/s}^{2} \cdot \cos (1.15)}

Next Step Prepare to Evaluate

∴

T = \frac{150}{0.5 \cdot 1000 \cdot 5 \cdot 2 \cdot {0.2023}^{2} \cdot \cos (1.15)}

Next Step Evaluate

∴

T = 1.79469731350996m

LAST Step Rounding Answer

∴

T = 1.7947m
