Syllabus / What will i learn?

Course Objectives:

-Students who take this class can expect to Develop an appreciation for the properties of Newtonian fluids.

-Study analytical solutions to variety of simplified problems.

-Understand the dynamics of fluid flows and the governing non-dimensional parameters.

-Apply concepts of mass, momentum and energy conservation to flows.

-Grasp the basic ideas of turbulence.

Course Outcomes: At the end of the course, the student will be able to:

  • Apply conservation laws to derive governing equations of fluid flows.
  • Compute hydrostatic and hydrodynamic forces.
  • Analyze and design simple pipe systems.
  • Apply principles of dimensional analysis to design experiments.
  • Compute drag and lift coefficients.

UNIT - I

Introduction: Dimensions and units – Physical properties of fluids specific gravity, viscosity, surface tension, vapor pressure and their influences on fluid motion pressure at a point, Pascal’s law, Hydrostatic law - atmospheric, gauge and vacuum pressure- measurement of pressure. Pressure gauges, Manometers: differential and Micro Manometers. Hydrostatic forces on submerged plane, Horizontal, Vertical, inclined and curved surfaces – Center of pressure. Derivations and problems.

UNTI – II

Buoyancy and floatation: stability of bodies, meta centre, liquids in relative equilibrium.
