L means same time.
Explanation:
Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.
