MEC 3120 - Fluid Mechanics3 lecture hours 0 lab hours 3 credits
Course Description
This course covers the fundamental tools needed for analyzing fluid mechanics problems. Approaches for solving engineering problems involving static and moving fluids are covered. The theory developed will allow students to pursue advance practice in fluid dynamics (e.g., computational fluid dynamics and aerodynamics). (prereq: MEC 2020 , MTH 2130 , MTH 2140 ) (quarter system prereq: ME 2002, MA 2323, MA 235, PH 2031)
