PROTÓTIPO: SISTEMA DE ABASTECIMENTO ENTRE RESERVATÓRIOS E COMPARATIVO ENTRE TUBOS

Abstract

This paper presents an investigation of hydrosanitary systems in multi-storey buildings, emphasizing water transfer between reservoirs and the comparison of pipe materials. The main aim was to assess the effect of head loss on hydraulic and energy performance across different materials. The research comprised two stages: building a physical prototype and conducting practical trials. PVC and galvanized iron pipes were tested, with discussion on alternatives such as PPR and PEX. Head losses were estimated using the Darcy–Weisbach and Hazen–Williams formulations. The findings indicate that smoother materials like PVC, PPR and PEX yield superior hydraulic and energetic performance, whereas galvanized iron, though durable, shows increasing head loss over time due to buildup. It is concluded that choosing appropriate materials and following updated technical standards (NBR 5626:2020, NBR 12217, NBR 15527) supports sustainability, cost reduction and efficiency in hydrosanitary design.
