Propeller efficiency, best way to get fan performance curve?

Can someone evaluate my project? I calculated volume flow at both ends of the pipe so i can do parapetric study with pressure drop. At calculated volume flow i should get pressure drop close to 0 but after 55 travels i still get 11268 Pa. Normaly i would do 20 parametric points with volume flow from 0,01 m^3/s to calculated volume flow from first study. Is this a way to calculate propeller efficiency? I want to use it later as a fan in a tank, so i can evaluate different angles of a blade and choose best mixing option.
