 Engineering Knowledge: Engineering Sciences ## Engineering Performance Matrix

Fluid Mechanics concerns how the laws of force and motion apply to liquids and gases. This concept is important to Engineering Literacy, as it is the knowledge that informs how engineering professionals understand, design, create, and analyze systems involving fluids such as heating and cooling equipment, pump systems, fans, turbines, pneumatic equipment, and hydraulic equipment. For example, one may use Bernoulli’s equation and the conservation of mass to determine flow rates, pressure changes, minor and major head losses for viscous flows through pipes and ducts, and the effects of pumps, fans, and blowers in such system.
