JNTUK R20 B.Tech FM & HM Material – Outcomes

Understanding Fluid Properties: Students learn about the fundamental properties of fluids, such as density, viscosity, and pressure, and how they affect fluid behavior.

Mechanics of Fluids in Static and Dynamic Conditions: Students understand how fluids behave in both static situations, like in tanks, and dynamic conditions, such as flow in pipes or channels.

Boundary Layer Theory and Flow Separation: Students study boundary layer theory, which explains how fluids flow near solid surfaces, and flow separation phenomena, where fluid flow separates from a surface. They also learn about dimensional analysis to understand and predict fluid behavior.

Hydrodynamic Forces of Jets on Vanes: Students analyze how jets of fluid impact vanes in different positions, studying the forces exerted and how they affect the vane’s motion and stability.

Working Principles of Hydraulic Pumps and Turbines: Students explore the working principles of hydraulic pumps, which move fluids, and turbines, which generate power from fluid flow. They also evaluate the performance of these devices in various applications.
