Re: ABOUT how fast does water evaporate this time of year in Texas?

There is no real answer for your question. Water does not evaporate at 
different rates in Texas than it does anywhere else. Water evaporation rate 
depends on only a few factors:

-temperature - water evaporates more quickly when it is warm than when it is 
cold

- relative humidity - water evaporates more quickly when the RH is low than 
it does when it is high

- air motion - water will evaporate more quickly if the air above it is 
constantly being replaced, given that the temperature is above freezing and 
the RH is low 

Case in point: water can evaporate more quickly in the summer above the 
Arctic Circle than it might in Houston in the winter.
