Present inquiry explores steady electro magneto hydrodynamic flow on porous exponentially vertical cone of Casson Williamson nanofluid. In this novel research work, we have successfully developed a multipurpose and adaptable penta-hybrid nanofluid by mixing nanoparticles of silver (Ag), gold (Au), magnesium oxide (MgO), copper (Cu), titanium dioxide (TiO2) with base fluid and are used in many innovative applications, including coatings, sensors, energy storage, water purification, enhanced heat transfer, biological purposes and lubricants. Numerous industries can benefit considerably from the combined features of these nanoparticles, which can improve the base fluid’s functioning and performance. Further, it aims to determine thermal and mass transportation of penta-hybrid nanofluid. The controlling PDEs can be turned into non-linear ODEs via similarity conversions, solved using fifth order Runge-Kutta-Fehlberg technique via shooting technique. Penta-hybrid nanofluid/ C2H6O2is excelled in heat transport to greater extent than other hybrid nanofluids with 62.6 %. Moreover, entropy generation rate is performed, and irreversibility demonstrates that, compared to previous efforts, total entropy generation rate minimize energy loss by 247.16 % in present study. Estimating impact of flow patterns and transmission rates are useful application with varied industrial and engineering applications, environmental restoration, and biomedical applications such as targeted medication administration.
