Course Learning Outcomes. Students will:

1. Knowledge of basic properties of fluids: density, viscosity, surface tension, vapor pressure, ideal gas law, their definitions, variation with temperature and pressure, use of tables. Dimensional analysis.

2. Understanding the concept of pressure as a point function and the basic equation of hydrostatics: balance of pressure gradient with gravity and general body forces. Pressure measurement, gage pressure and absolution pressure, manometers.

3. Use of the equation of hydrostatics to determine pressure distributions over arbitrary wetted surfaces, including fluids with rigid-body rotation. Understanding the physical origin of buoyancy and being able to calculate buoyancy forces in fluids at rest and also in solid-body motion.

4. Understanding and ability to apply the one-dimensional continuity equation and Bernoulli’s equation to solve flow problems

5. Understanding Fluid Kinematics: Eulerian and Lagrangian Flow descriptions, one, two, three-dimensional flows, steady, unsteady flows, streamlines, streaklines, and pathlines, calculation of fluid acceleration, material derivative. Control volume and System Representation: Reynolds transport equations. Conservative and Differential form of the flow equations.

6. Use Control Volume Analysis: mass, momentum, and energy equations to solve practical flow problems.

7. Differential form of the basic fluid dynamic equations: mass, momentum, and energy equations, Bernoulli’s equation. Stream functions, irrotational flow, potential function, souces, doublets, and vorties.
