1Coefficient of performance — The coefficient of performance or COP (sometimes CP), of a heat pump is the ratio of the change in heat at the output (the heat reservoir of interest) to the supplied work. Contents 1 Equation 2 Derivation 3 Improving COP 4 …
2Coefficient of Performance — (COP) A ratio of the work or useful energy output of a system versus the amount of work or energy inputted into the system as determined by using the same energy equivalents for energy in and out. Is used as a measure of the steady state… …
3Gini coefficient — The Gini coefficient is a measure of statistical dispersion most prominently used as a measure of inequality of income distribution or inequality of wealth distribution. It is defined as a ratio with values between 0 and 1: A low Gini coefficient …
4Temperature coefficient — The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K. In the following formula, let R be the physical property to be measured and T be the temperature at which the property is… …
5Positive temperature coefficient — (PTC) refers to materials that experience an increase in electrical resistance when their temperature is raised. Materials which have useful engineering applications usually show a relatively rapid increase with temperature, i.e. a higher… …
6Ballistic coefficient — The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the deceleration mdash;a high number indicates a low deceleration. BC is a function of mass, diameter, and… …
7Pressure coefficient — The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own …
8Partition coefficient — In chemistry and the pharmaceutical sciences, a partition (P) or distribution coefficient (D) is the ratio of concentrations of a compound in the two phases of a mixture of two immiscible solvents at equilibrium.[1] The terms gas/liquid partition …
9Attenuation coefficient — For attenuation coefficient as it applies to electromagnetic theory and telecommunications see propagation constant. For the mass attenuation coefficient , see the article mass attenuation coefficient. The attenuation coefficient is a quantity… …
10Void coefficient — In nuclear engineering, the void coefficient (more properly called void coefficient of reactivity ) is a number that can be used to estimate how much the reactivity of a nuclear reactor changes as voids (steam bubbles) form in the reactor… …
