In Maths, inverse variation is the relationships between variables that are represented in the form of y = k/x, where x and y are two variables and k is the constant value. Flow Visualization When the value of a quantity does not change under different conditions, it is constant. In notation, inverse variation is written as . We say y varies directly with x (or as x , in some textbooks) if: y = k x for some constant k , called the constant of variation or constant of proportionality . The Boltzmann constant (k B or k) is the proportionality factor that relates the average relative kinetic energy of particles in a gas with the thermodynamic temperature of the gas. In this case, k = 0.16 k = 0.16 and n = 1. n = 1. Use this free online constant of variation calculator to generate equation based on the given x and y values. F0 Value in Steam Sterilization A constant of proportionality, also referred to as a constant of variation, is a constant value denoted using the variable "k," that relates two variables in either direct or inverse variation..
