nnAs you will know, computer assisted drawing software (CAD) has the main objective of increasing productivity when making molding, which makes them an excellent choice for engineers. But it is also well known that the main disadvantage of these programs is that their usage licenses are extremely expensive, which makes them only accessible to companies…

When designing pipe, the behaviour of the network elements and a query that always appears at the time of calculate the loss of load or piezometric height in a pipe due to friction through the passage of water -which must logically be calculated when designing with EPANET- is what are the loss coefficients to use.nnThis…

Water is the factor that dramatically differentiates the earth from the other planets, although the total water supply has remained constant for millions of years, it never remains stationary, it is the most active material on Earth and that is what we will see in this entry, the water cycle. No, no, no, no, no,…

Excellent manual regarding the design of septic tanks and stabilization lagoons, carried out by the Pan American Health Organization and COSUDE, as a summary, I can tell you that septic tanks are used for the treatment of waste water in localities or places where there is no access to the sewage service. It is important…

According to the Federal Council for Science and Technology: Hydrology deals with the water of the Earth, its existence and distribution, its physical and chemical properties, and its influence on the environment, including its relationship with living beings. The domain of hydrology encompasses the complete history of water on Earth.

The use of the rational formula or rational method is far from one of the most used methods for estimating the maximum flow associated with a design rain, mainly because it does not require a large amount of hydrometric data for the determination of maximum flood flows, yes, it is always important to take into…
