4 Course Learning Outcomes The Fluid Mechanics Laboratory experiments are set up so that experiments can be performed to complement the theoretical information taught in the fluid mechanics lecture course. Thus topical areas have been identified and labeled as Course Learning Outcomes (CLOs). The CLOs in the MECH 3335 Laboratory are as follows: TABLE 1. Course Learning Outcomes 1. Identify safe operating practices and requirements for laboratory experiments 2. Measure fluid properties 3. Measure hydrostatic forces on a submerged body 4. Use flow meters to measure flow rate in a pipe 5. Measure pressure loss due to friction for pipe flow 6. Measure drag/lift forces on objects in a flow, or measure flow rate over a weir 7. Design and conduct an experiment, as well as analyze and interpret data 8. Function effectively as a member of a team Cleanliness There are “housekeeping” rules that the user of the laboratory should be aware of and abide by. Equipment in the lab is delicate and each piece is used extensively for 2 or 3 weeks per semester. During the remaining time, each apparatus just sits there, literally collecting dust.
