Equivalent circulating density

Input(s)

$\rho_{\mathrm{m}}$: Mud Weight (ppg)

$\delta \mathrm{P}_{\mathrm{a}}$: Annulus Pressure Loss (psi)

$\mathrm{L}_{\mathrm{t}}$: True Vertical Depth $(\mathrm{ft})$

Output(s)

ECD: Equivalent Circulating Density (ppg) (ppg)

Formula(s)

$$ \mathrm{ECD}=\rho_{\mathrm{m}}+\left(\frac{\delta \mathrm{P}_{\mathrm{a}}}{0.052 * \mathrm{~L}_{\mathrm{t}}}\right) $$
