Buoyancy weight
Input(s)
\(\rho_{\mathrm{m}}\): Density of Mud \((\mathrm{ppg})\)
\(\rho_{\mathrm{s}}\): Density of Pipe Material \((\mathrm{ppg})\)
\(\mathrm{d}\): Depth \((\mathrm{ft})\)
m: Weight (ppf)
Output(s)
B: Buoyancy Factor (fraction)
W: Buoyancy Weight (lbf)
Formula(s)
\[
\begin{gathered}
\mathrm{B}=\left(1-\left(\frac{\rho_{\mathrm{m}}}{\rho_{\mathrm{s}}}\right)\right) \\
\mathrm{W}=\mathrm{B} * \mathrm{~m} * \mathrm{~d}
\end{gathered}
\]
