Abstract

The document titled "Comment on Vishalakshi et al. MHD Hybrid Nanofluid Flow over a Stretching/Shrinking Sheet with Skin Friction: Effects of Radiation and Mass Transpiration" criticizes two errors in a previous publication. The first error is related to an incorrect gravity term in an equation, which violates the known physics principle that gravity acts in the vertical direction. The second error involves a dimensional inconsistency in an equation, where some parameters are dimensionless while one parameter is dimensional. The document concludes by stating that the authors have no conflicts of interest. [Extracted from the article]
