Annulus Pressure Loss Due to Friction During Hydraulic Fracturing - Laminar Flow Calculator

ΔPf=μpLv1000(d0−di)2+τyL200(d0−di)\Delta P_f=\frac{\mu_pLv}{1000(d_0-d_i)^2}+\frac{\tau_yL}{200(d_0-d_i)}

Enter the required inputs, confirm the units, and run the calculator to solve DeltaP_f. Review the formula source and assumptions before using the result in engineering work.
