The document discusses the dimensional and dimensionless momentum equations presented in a paper by Nawaz et al. The equations describe fluid flows in boundary layers. The document highlights the differences between the dimensional equation and the dimensionless equations, particularly in terms of the time derivative. It points out that the fractional parameter is absent in the dimensional equation, suggesting that the two terms are not compatible. The given text discusses the compatibility between the dimensional and dimensionless equations for fluid flow. It also identifies errors in equations presented in a study by Nawaz et al., including terms with different units and incorrect values of alpha. The authors of the study declare no conflicts of interest. [Extracted from the article]
