Generally, the larger the evaporating flask, the greater the evaporation rate. This is because a larger flask allows for an increased velocity at the perimeter of the flask. With higher speed, the solvent inside the flask becomes more agitated and the active surface area of the solvent is enlarged. This all results in a higher evaporation output.
