The design flow of an installation is 100L / s and the linear and localized losses add up to 25 m. c.a over 100 meters of pipe with a diameter of 150 mm. Considering this, we ask: -Is the installation machine a pump or turbine? - In the design of hydraulic installations, it is necessary to avoid the phenomenon of cavitation (formation, vaporization and implosion of bubbles) that generally causes wear, vibrations and loss of equipment performance. This occurs when the pressure absolute pressure falls below the vapor pressure of the flowing fluid at a given temperature (vapor pressure (water at 30 ° C), Pv = 4.3 kPa). So said, at what maximum distance from the reservoir can the equipment be allocated? Note: Solve the problem using the classic integral formulation based on the 1st Principle of Thermodynamics.
