Upon successful completion of this course, students should be able to:

  1. Describe the scope of fluid mechanics. 
  2. Calculate the hydrostatic forces, pressures and moments on planar and curved submerged and floating surfaces.
  3. Decide when it is appropriate to use ideal flow concepts and the Bernoulli equation.
  4. 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.
  5. Present data or governing equations in non-dimensional form and apply dimensional analysis.
  6. Solve for internal flow in pipes and channels through simple solutions of the Navier-Stokes equations, the Moody chart and the head-loss equation.
  7. Solve for external (laminar and turbulent boundary layer) flows, evaluate lift and drag, know when there is possibility of flow separation.
  8. 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.
