JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Prerequisites

Engineering Mathematics, Engineering Physics

Course Objective

To introduce the concepts, principles, laws, observations and models of

fluids at rest and in motion and also to provide the basis for understanding the fluid behavior, engineering design and control of fluid systems.

Course Outcomes

The student would be able to get knowledge related to compressible &

incompressible fluids and also transportation of fluids.
