Principle

The efficiency attained in this experiment, only 2 % to 3 %, is
very low compared to that of pumps used in practice, which can
reach 20 % to 90 %. This difference is mainly due to the size of
the pump and, in particular and despite the small scale of it, the
fact that the robustness needed for the stability of the rotor is
attained at the cost of the performance.

The purpose of this experiment is to bring home the efficiency
calculation.
