Conduction shape factor
The heat transfer from one surface (at a temperature T1) to the other surface (at T2) can be expressed as: q=Sk(T1-T2) where k is the thermal conductivity of the solid and S is the conduction shape factor.
Example: 1-D heat transfer can use shape factor also.

Efficiency
noun
Efficiency signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output. Efficiency requires reducing the number of unnecessary resources used to produce a given output including personal time and energy. It is a measurable concept that can be determined using the ratio of useful output to total input. It minimizes the waste of resources such as physical materials, energy, and time while accomplishing the desired output.
Example: efficiency can be used in a variety of ways to describe various optimization processes.
es: Eficiencia
Fin effectiveness
noun
The fin temperature effectiveness or fin efficiency is defined as the ratio of the actual heat transfer rate through the fin base divided by the maximum possible heat transfer rate through the fin base, which can be obtained if the entire fin is at base temperature
Example: The efficiency of a fin is defined as the ratio of the actual heat transfer
es: Eficacia de la aleta
Fin efficiency
noun
Fin efficiency is defined as the ratio of actual heat flow of the fin to that which would be obtained with a fin of constant temperature uniformly equal to the base surface temperature, that is, one with infinite thermal conductivity.
Example: Fin efficiency is defined as the ratio of actual heat flow
es: Eficiencia de las aletas
Interface resistance
phrase
The interfacial resistance between PEM and electrode can be used as a metric to quantify interfacial compatibility. Interfacial resistance can be obtained from a cell resistance plot as a function of membrane thickness under fully hydrated conditions, where HFR increases due to PEM dehydration can be ruled out.
Example: To identify possible interfacial resistance to mass transfer by an adsorbed surfactant layer,
es: Resistencia de interfaz
Plane wall conduction resistance
phrase
is the thermal resistance of the wall against heat conduction or simply the conduction resistance of the wall
Example: let us consider a plane wall of homogeneus material througt which heat is flowin in x direction
es: Resistencia a la conducción de la pared plana
Radiation resistance
phrase
the component of antenna resistance that accounts for the power radiated into space and is equal in ohms to the radiated power in watts divided by the square of the effective current in amperes at the point of power supply
Example: Radiation resistance is that part of an antenna's feedpoint electrical resistance that is caused by the radiation of electromagnetic waves from the antenna.
es: Resistencia a la radiación
Sphere conduction resistance
phrase
This property studies the transfer of heat in a body with the shape of a sphere
Example: simply the conduction resistance of the spherical layer.
es: Resistencia a la conducción de la esfera
Surfaces
noun
the exterior or upper boundary of an object or body
Example: on the surface of the water
es: Superficies
