Course Objectives: (numbers in parentheses indicate relationship to engineering program outcomes)

                                                 

At the completion of the course, students will have demonstrated the ability to

 

·         use both the English and SI systems of units, including conversions within and between them (1);

·         determine pressure differences from fluid heights in manometers (1);

·         calculate hydrostatic forces on submerged surfaces and buoyancy forces on submerged and partially-submerged objects (1, 2);

·         derive acceleration fields from velocity fields and determine whether flows satisfy differential continuity and are irroatational (1, 2);

·         recognize when the use of Bernoulli’s equation is appropriate, and apply Bernoulli’s equation to determine unknown pressures, velocities, or elevations in a flow field or system (2);

·         select appropriate control volumes and apply the integral continuity, momentum, and energy equations to determine average fluid velocities, flow rates, resultant forces, and energy/power inputs/outputs (e.g., pump power requirements) for fluid systems (1, 2);

·         calculate skin-friction forces on flat plates (2);

·         determine which dimensionless parameters should be held constant to achieve similitude in model tests, and use these parameters to predict prototype performance from model test data (2);

·         calculate head losses in pipes, inlets, exits, and fittings (2);

·         calculate flow rates in simple open channel flows (2);

·         determine lift and drag forces on objects (2).
