##### Textbooks

Munson, Young, Okiishi and Huebsch, Fundamentals of Fluid Mechanics, 8th Edition, John Wiley & Sons.

##### Goals

To teach students the basic knowledge of fluid statics and fluid dynamics for cases of non-viscous and viscous fluids and for cases of incompressible as well as compressible flow.

##### Outcomes

**After completion of this course, the students should be able to:**

- Describe the scope of fluid mechanics [a].
- Calculate the hydrostatic forces, pressures and moments on planar and curved submerged and floating surfaces [a, k].
- Decide when it is appropriate to use ideal flow concepts and the Bernoulli equation [a].
- Construct an appropriate control volume for a given engineering system and apply the principles of conservation of mass, momentum, and energy to this control volume in differential and integral forms [a].
- Present data or governing equations in non-dimensional form and apply dimensional analysis [a].
- Solve for internal flow in pipes and channels through simple solutions of the Navier-Stokes equations, the Moody chart and the head-loss equation [a].
- Solve for external (laminar and turbulent boundary layer) flows, evaluate lift and drag, know when there is possibility of flow separation [a].
- Describe the propagation of sound; apply the basic equations of 1D, steady compressible flow and isentropic flow with area change to solve for unknown properties using appropriate property relations [a, k]
