Macleod equation and constant in pure, binary and ternary systems
The Macleod equation establishes a linear relationship between surface tension and the fourth power of the density difference between liquid and vapor, expressed asσ=CMacleod(ρl−ρv)4. This study demonstrates by a practical and empirical approximation with critical exponents and the theory of corresp...

| description | The Macleod equation establishes a linear relationship between surface tension and the fourth power of the density difference between liquid and vapor, expressed asσ=CMacleod(ρl−ρv)4. This study demonstrates by a practical and empirical approximation with critical exponents and the theory of corresponding states, the foundations behind Macleod's proposal and extends this equation to binary and ternary systems exhibiting liquid-liquid equilibrium. Additionally, it offers a thermodynamic perspective on the Macleod constant through a novel variable termed the entropic molar volume, along with other functions. |
