    Backup Water System Design for Off the Grid Housing
    (Polytechnic University of Puerto Rico, 2024) González Pérez, Niomarie; Peláez Carpio, Hugo
    This study designs and analyzes a backup water distribution system for off-grid housing in response to Puerto Rico’s unreliable electrical grid. The system includes a ravine water source, a 600-gallon storage tank, and an energy efficient piping and pump design. Using Computational Fluid Dynamics (CFD) in COMSOL Multiphysics, key parameters such as pressure distribution, velocity profiles, volumetric flow rate, and Reynolds number were evaluated. Results indicate maximum pressure at the inlet due to the pump and minimum pressure at the outlet from elevation changes and pipe bends. A steady velocity profile and consistent volumetric flow rate confirm system stability. The Reynolds number (1.55×10⁵) indicates turbulent flow, ensuring efficient energy dissipation. The system meets performance criteria, providing efficient water transport with minimal energy consumption. Future improvements include integrating a submersible pump and further optimization to enhance system efficiency for sustainable off-grid applications.

    Estudio Hidrológico - Hidráulico (H-H) para Puente Localizado en Río Grande P.R.
    (Polytechnic University of Puerto Rico, 2024) Castillo Rivera, Carlos; Villalta Calderón, Christian
    Como parte del estudio hidrológico - hidráulico en el Bo. Mameyes de Río Grande P.R., se realizó un análisis en la cuenca del Río Mameyes utilizando los programas de QGIS, HEC- HMS y HEC – RAS [1]. El estudio hidrológico e hidráulico consistió en realizar un análisis en la cuenca del Río Mameyes, el cual nos permitirá en un futuro tener un panorama más preciso de las áreas afectas por inundaciones en esta comunidad. Para el análisis se delimito la cuenca de la zona utilizando un área de 13.264 mi2 y se consideraron eventos de lluvias temporales para duraciones de 1, 6, 12, y 24 horas; para inundaciones desde 2 hasta 100 años. Para realizar el análisis hidráulico, se utilizó el programa del Sistema de Análisis de Ríos (HEC RAS) del Centro de Ingeniería Hidrológica del Cuerpo de Ingenieros del Ejército de los Estados Unidos para simular y analizar las diversas condiciones de inundación producidas por los eventos de lluvias. En la cuenca del Río, se estimaron caudales máximos de aproximadamente 16,453 metros cúbicos por segundo para la precipitación máxima probable de 24 horas y 100 años. Los resultados del modelo indican que el evento de lluvia causaría inundaciones en muchas propiedades a lo largo del tramo de la PR #191 hasta el puente ubicado en la PR #3, pero estas no afectarían la estructura del puente. Sin embargo, sería buena práctica realizar inspecciones anuales para monitorear las sovocaciones y posibles fallas futura. Key Terms - Geographical Information System, QGIS, HEC-HMS, HEC-RAS
