The formula to calculate the Dirty Volume (Vd) is:
\[ V_{d} = \frac{V_{n}}{1 - P_{bsw}} \]
Where:
Let's say the net volume (Vn) is 100 cubic meters and the basic sediment and water percentage (Pbsw) is 0.1. Using the formula:
\[ V_{d} = \frac{100}{1 - 0.1} = \frac{100}{0.9} = 111.11 \]
So, the Dirty Volume (Vd) is 111.11 cubic meters.
