Yes, you can calculate the friction losses using the Darcy-Weisbach equation. The pressure losses are proportional to the length of the pipe and the Darcy-Weisbach friction factor:

delta_P / L = f_D * (rho / 2) * (V_avg^2 / D )

where,

delta_P - pressure drop

L - pipe length

f_D - friction factor

rho - fluid density

mu - fluid dynamic viscosity

V_avg - average fluid velocity

D - pipe diameter


This equation is valid for incompressible flows.
