How long does water evaporation take? what factors influence it?

There is no certain time on how long it takes. Because the factors will always be different and the factors heavily affect the evaporation time. Some factors include: humidity, heat, how the sun is visible (whether clouds are covering it or not)

There is not any fix time for evaporation...every liquid has different boiling pointwhen any liquid boils completely then it start evaporating.

Six factors that influence evaporation are :-
(1) Wind assists evaporation
(2) Heat assists evaporation
(3) Increase in surface area exposed assists evaporation
(4) Dryness assists evaporation
(5) Rate of evaporation depends upon the nature of the liquid
(6) Vapor pressure
