Equation for Gross Water Draft Solution

Follow our step by step solution on how to calculate Equation for Gross Water Draft?

FIRST Step Consider the formula

D G = R G - B + I s + I - (h \cdot S Y \cdot A)

Next Step Substitute values of Variables

∴

D G = 45m³/s - 6m³/s + 18m³/s + 12m³/s - (5m \cdot 0.59 \cdot 20m²)

Next Step Prepare to Evaluate

∴

D G = 45 - 6 + 18 + 12 - (5 \cdot 0.59 \cdot 20)

LAST Step Evaluate

∴

D G = 10m³/s
