Efficiency of the pump in the conversion of electric energy to potential energy 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. Benefits - Experiment is part of a complete solution set with a total of 26 experiments for Renewable Energy solar cells, wind power, water power
- Safe experimentation: The fan in the blower is protected against touch
- The power supply used is versatile and is particularly suitable for pupil tests for all ages
