Designing water fluid circuits

Designing a system which circulates water requires mastering the theoretical basis of the mechanics of fluids. This article presents the minimum knowledge required. It thus details the physical notions and the principles which govern the behavior of water in such circuits: hydraulic quantities (viscosity, compressibility, thermosyphons), principles of transfer of heat (convection, conduction, radiation), notions related to filtration (clogging, filtrate, suspension, etc.), chemical quantities and laws (Henry's law, crystallization, water pH, etc.) and characteristics of pipes (pressure, diameter, etc.)
