Subsea considerations - Choke line pressure loss

Input(s)

$W_{m}$: Mud Weight (ppg)

L: Choke Line Length (ft)

$R_{c}$: Circulation Rate $(\mathrm{gpm})$

$D_{i}$: Choke Line ID (in.)

Output(s)

CLPL: Choke Line Pressure Loss (psi)

Formula(s)

$$ C L P L=\frac{0.000061 * W_{m} * L *\left(R_{c}^{1.86}\right)}{D_{i}^{4.86}} $$
