Principle of Hydraulic Machines and System Design

  • Course level: Beginner

Description

The principle of operation of hydraulic machines and their system design is important from the perspective of their huge applications in different industries.

The present course introduces the students to the fundamentals of hydraulic machines. Starting from the operational principle, students will be gradually familiarized with different concepts like velocity triangle, net head developed, finally leading to the design of their system.  Important topics such as the design of the pumping system of two dissimilar pumps, which find practical relevance as well, will also be discussed.
INTENDED AUDIENCE: Undergraduate students of Mechanical/Electrical/Civil Engg. (5th semester onwards) and postgraduate students specializing in the thermofluids/Fluid Mechanics; industry personnel associated with pump industries; faculty members associated with Mechanical/Electrical/Civil Engg
