You only have to look at the major search engines to see how popular and valuable dehydrated.com is.
For example, Google has 188,000 results for dehydrated.
There are many applications a company could use dehydrated.com for :
sell or market food dehydrators
sell or market bulk dehydrated food
sell or market medical products and services related to dehydration - because its a fact, a large % of the popluation is dehydrated
sell or market sports drinks and supplements.
Dont forget - what someone as an indivdual would pay is far less than what a company in the relevant industry would pay for a particular domain. So altogether I think it adds up to you having a very valuable domain. I would say you could get up to $1500-$5000 range, if you were able to get multiple bidders bidding on it.
