Specific power refers to the power output or consumption per unit of some specific parameter, such as mass or volume. Specific power” is the measure of power output per unit mass or volume, expressed typically in watts per kilogram or watts per liter.
Engineers and physicists commonly use it to evaluate the efficiency or performance of various devices or systems, such as engines, batteries, or electric motors. By calculating specific power, engineers can assess the energy density and effectiveness of a particular technology, aiding in the design and optimization of systems for specific applications.
