Abstract

This work describes a methodological process to estimate the precipitable water for human consumption as a function of meteorological parameters like ambient and dew point temperature, water vapor and ambient pressure, and relative humidity. The paper uses empirical correlations to determine the most accurate procedure for atmospheric rainwater, resulting in a simple relation between precipitable water and dew point temperature as the highest accurate one. The study shows the dew point temperature dependence on vapor pressure and relative humidity, concluding that measuring air temperature and humidity, precipitable water amount can be determined using the developed algorithm. The study analyzes different climates, dry, medium and humid, to determine the required water collection surface to cover daily human water needs. It also concludes that dry climates with relative humidity below 20% are inappropriate and should be discarded. This work includes an engineering development of water collector device, which results in a modular unit whose size depends on the water requirements and geographical zone humidity. The size and shape are optimized to minimize the water collector module number, reducing building costs and simplifying the manufacturing process. The modular unit size is foldable, easy to handle, and requires low storage room.
