The stress at which a specific amount of plastic deformation is produced, marking the transition from elastic to plastic behavior.

A measure of the force that can cause an object to rotate about an axis.

A measure of a fluid's resistance to gradual deformation by shear stress or tensile stress.

The branch of physics that deals with the relationships between heat and other forms of energy.

A principle stating that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.

The reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend.

A dimensionless quantity used to characterize fluid flow by comparing the relative influence of inertial effects and viscous effects.

A fluid property defined as dynamic viscosity divided by fluid density, representing the fluid's viscous behavior relative to its density.

The loss of mechanical energy per unit weight of flowing fluid caused by frictional effects during flow through a pipe or conduit.

A dimensionless factor used in the Darcy-Weisbach relationship to represent the effect of pipe-wall friction on frictional head loss.

The volume of fluid which passes per unit time.

The area of a two-dimensional shape that is obtained when a three-dimensional object - such as a pipe - is sliced perpendicular to some specified axis.

The average macroscopic speed of a fluid in a confined flow system, calculated as volumetric flow rate divided by cross-sectional area.

Basic operations of numbers including addition, subtraction, multiplication, and division.

A number or ratio expressed as a fraction of 100.

Mathematical operations involving exponents and extracting roots.

A method of writing very large or very small numbers using powers of 10.

Mathematical phrases that can contain numbers, variables, and operators.

A relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

The study of flat, two-dimensional shapes like lines, circles, and triangles.

The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.

Standardized quantities used to express physical measurements and their fundamental nature.

The total amount a specific dimension is permitted to vary, representing the difference between the maximum and minimum limits.

A system for defining and communicating engineering tolerances that uses a symbolic language to explicitly describe nominal geometry and its allowable variation.
