Subject Title
Fluid Mechanics

Subject Description
This course provides an introduction to fluid mechanics. Topics of fluid statics covered include pressure scales, the hydrostatic equation, manometry, forces on submerged surfaces, and buoyancy. In fluid dynamics students study the equation of the conservation of mass, Bernoulli's equation, the general energy equation, and the power delivered to or removed from a flowing fluid by a pump or motor. They also learn about viscosity, laminar flow and turbulent flow, and energy losses in pipes.  Students use their knowledge of fluids in motion to solve flow problems occurring in involved pipe systems. The course concludes with topics of special interest to aviation students: boundary layers on flat plates, the drag on both streamlined and bluff bodies and the lift and drag on some NACA airfoils. 

Credit Status

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Define the quantities weight density, mass density and relative density (specific gravity) and calculate these quantities for various substances.

2. Define pressure. The student will also be able to define absolute pressure, gauge pressure and vacuum pressure and convert a pressure given in one scale to pressures in the two other scales.

3. Derive the hydrostatic equation and use it to solve problems in manometry.

4. Use the hydrostatic equation to calculate the forces on submerged rectangular surfaces.

5. Use Archimedes principle to calculate buoyant forces and hence solve involved statics problems where buoyant forces are present.

6. Use the principle of continuity and Bernoulli’s equation for incompressible flow to solve simple problems involving frictionless incompressible flow through a pipe, an orifice or a venturi meter.

7. Apply the general energy equation to pipe systems in which energy is dissipated by friction etc. and which contain devices such as pumps, turbines, etc. which add or remove energy from the fluid. The student will be able to calculate the rate that energy is added to or removed from flowing fluids by such machines.

8. Describe the properties of both laminar flow and turbulent flow and determine which type of flow obtains for a given flow rate in a given pipe by evaluating the Reynolds number for the flow.

9. Estimate the energy lost due to friction in pipe systems by using either the Moody diagram to estimate the friction factor f or using an analytic expression for f .

10. Estimate the minor losses due to fittings or changes in geometry in a given pipe system with a given flow rate.

11. Use their acquired knowledge to solve problems involving complicated class I and class II pipe systems.

12. Calculate the forces exerted by fluid jets on vanes and the forces exerted by pipe bends and other pipe geometries on flowing fluids.

13. Describe the properties of fluid boundary layers for flow over a flat plate with no pressure gradient and calculate the thickness of a completely laminar or completely turbulent boundary layer at a given distance from the leading edge of a flat plate.

14. Calculate the skin friction drag on a given flat plate caused by a completely laminar boundary layer, a completely turbulent boundary layer or a boundary layer which is partially laminar and partially turbulent.

15. Define lift and drag on an object in a moving fluid and calculate the total fluid drag on some simple geometric shapes using empirical values of drag coefficients.

16. Calculate the lift and drag on some NACA airfoils using NACA empirical airfoil data.

17. Carefully measure quantities such as pressure, flow rate, etc. using various types of fluid mechanics apparatus. Interpret the significance of experimental results and comment on and estimate the errors in their results.
