Constant cross-section pipe area
L = \frac{1}{2 \, G \, c^* \rho^*} \cdot \ln \frac{G \, \rho^2-F}{G \, \rho_0^2-F} -\frac{d}{f} \cdot \ln \frac{F/\rho^2 - G}{ F/\rho_0^2-G}
\cos \theta \neq 0
L = \frac{1}{2F\, c^* \rho^*} \cdot (\rho_0^2 - \rho^2) - \frac{2d}{f} \cdot \ln \frac{\rho_0}{\rho}
\cos \theta = 0
