Avg score: 80% Most missed: “The three major fluid forces are Buoyancy, drag and lift.”
Dimensional and Model Analysis topics include: Dimensional homogenity, model analysis, dimensionless numbers, similarities types and laws, testing on submerged bodies, moving fluid types and model classifications. Dimensional analysis is a mathematical technique that helps establish empirical relationships for engineering problems and fluid flow. It's also known as the factor-label method or unit-factor method.  Dimensional analysis is based on the principle of dimensional homogeneity and uses the dimensions of relevant variables that affect the phenomenon. It's essential because it keeps... Show more
