Convection is the transfer of heat through a fluid (liquid or gas) by the movement of the fluid itself. When a fluid is heated, its particles gain energy and move faster, becoming less dense and rising. Cooler, denser fluid then ...
Bulk modulus is a measure of a material’s resistance to uniform compression. It is defined as the ratio of the applied pressure to the resulting relative volume change. A high bulk modulus indicates that the material is stiff and does ...
Stress is the force applied per unit area of a material. It is a measure of how much force a material can withstand without breaking or deforming. Stress is typically expressed in pascals (Pa) and can be tensile compressive or ...
Cross-sectional refers to the shape or area of an object when it is cut perpendicular to its length. In physics, it is used to describe the area through which forces, fluids, or electrical currents flow. It is important in calculating ...
