Hydraulic Turbomachines

About this course

The subject Hydraulic Turbomachines describes the operation of the group of machines that are governed by Euler’s principle (rotodynamic machines). The knowledge of these machines provides the basic principles necessary to analyze their behavior in any installation that they encounter, as well as the basic principles for their design and dimensioning.
