CAE 2711 - Fluid Mechanics2 lecture hours 2 lab hours 3 credits Course Description This course covers the basic principles of fluid mechanics necessary for the analysis and design of building plumbing and fire protection systems, air duct systems in building HVAC systems, and closed and open channel infrastructure. Specific topics will be covered using applicable case studies throughout the course. Students may not receive credit for both CAE 2711 and MEC 3120 . (prereq: MTH 1110 and PHY 1110 ) (quarter system prereq: MA 137) Course Learning Outcomes Upon successful completion of this course, the student will be able to:
- Calculate the pressure at any depth below the surface of a fluid (or fluids) and the magnitude and the point of application of hydrostatic forces acting on submerged surfaces
- Apply the equations of static equilibrium to objects submerged in or upon a fluid (i.e., buoyancy, stability, viscosity, surface tension, and drag problems)
- Analyze inviscid flow systems using the continuity and Bernoulli’s equations
- Calculate frictional energy losses in pipe using the Darcy-Weisbach and Hazen-Williams equations
- Calculate forces due to change in linear momentum in a system
- Analyze piping systems including pumps/turbines, pipe friction and minor losses using the General Energy equation
- Apply energy principles to measure flow rate in closed and open channel situations
- Determine the flow rate, head, and power requirements of centrifugal blowers and pumps at different operating point using (1) the affinity laws, and (2) manufacturer’s pump curves
- Analyze open channel flow problems using Manning’s equations and specific energy
