COURSE OBJECTIVES:
• To impart basic knowledge to the students about the open channel flows with analysis of uniform flow, gradually varied flow and rapidly varied flow and to expose them to basic principles of working of hydraulic machineries and to design Pelton wheel, Francis and Kaplan turbine, Centrifugal and Reciprocating pumps

We're excited to announce the launch of our new website! Visit NameWheelSpinner.com to explore its features and benefits.
