SUMMARY
The angle at which water droplets begin to roll down a glass plane is influenced by several factors, including the surface tension of the water, the smoothness of the glass, the type of glass used, and the presence of impurities such as detergents. A precise angle cannot be determined universally for all glass types due to these varying parameters. For projects like solar stills, understanding these factors is crucial for optimizing the angle of tilt for effective water purification.
