Morsi and Alexander's (MA) correlation represents the single-particle drag curve accurately. Ma and Ahmadi's correlation predicts values comparable with the MA correlation. Molerus' correlation deviates from the MA correlation at higher Reynolds numbers. Patel's correlation is found to give a better fit with the MA correlation than Richardson's correlation. Dalla Ville's correlation overpredicts values of drag coefficient compared to the MA correlation.
