      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]
