Avaliação da performance de um sistema de bombeamento de água acionado por propulsão humana.

Abstract

Pumps have been used to transport water from one location to another. These equipments can be powered by weathervanes, solar energy, electric motors and combustion engines. However, in regions where electricity is not available, you can use unconventional sources, such as human strength. Thus, this study ai am to evaluate the performance of a system of pumping operated by human propulsion. The procedure used was based on the optimization of an experimental system involving humans and the prototype under various operating conditions. Theoretical modeling to determine the efficiency of a piston pump and pumping system.Results of volumetric flowrate, force, torque, power and mechanical performance are presented and analyzed. The results show that the prototype is viable to conditions of pumping up 7m an volumetric flowrate of 0,700 m3/s.
