Hello everyone,

Is there an analytical expression to compute pressure drop in a circular pipe?

    Hello @Kremella  ,

    For an incompressible, laminar flow through a circular pipe, one can calculate the pressure drop using the Hagen-Poiseuille equation which is given below

    del_P = (8 * mu * L * Q) / (pi * R^4)

    where,

    del_P - pressure drop [Pa]

    mu - dynamic viscosity [Pa-s]

    L - pipe length [m]

    Q - volumetric flow rate [m^3/s]

    R - pipe radius [m]
