The course provides the basics of fluid streams motion and the tools for the design and verification of simple hydraulic systems
The course provides the fundamentals of the motion of fluid currents and the tools for the design and verification of simple hydraulic systems. In detail, it deals with the following topics: forces acting in a fluid at rest, the thrusts exerted by a fluid on flat and bumpy surfaces, the tension in a moving fluid and the principles that regulate the movement of a fluid current. On the basis of the topics discussed, exercises on the thrusts exerted by fluids and problems relating to simple systems are proposed.
