[TRNSYS-users] TRNSYS Rain Water Collection

[Fred Betz]

Has anyone ever modeled a rain water collection system in TRNSYS? 
 
Also, do the existing weather files support this type of simulation? If not, do you know where I might find hourly rain data?
 
On one weather file I was able to get (Sterling, VA, USA), there is a "Precipitable Water" value that doesn't have any units. 
 
I looked up precipitable water online and got the definition, "A quantity of water available in the atmosphere in a column".
 
That to me does not mean an amount of rain, but a potential amount of rain. 
 
Any help would be appreciated.
