Abstract: In this article,the pressure drop equation is derived for the laminar helical flow of the power law fluids in the eccentric annlular space and a method is introduced to calculate the pressure drop with the pressure drop equation.Also,the theoretical pressure drop calculated with the equation is compared with the theoretical pressure drop of the laminar helical flow in the concentric annular space.
