Hi everybody,
Can anyone direct me (a link /artical/ source-including in a post)
to info about the following:
Is there a formula that could be used to compute the relative chilling effect /relative heat loss (to a person) of air at a certain temp. vs water at that same temp.
i.e. "a water temp of ## degrees chills you as fast as an air temp. of ##degrees"?
This question arose as a result of a conversation with a few nondiving friends who wondered why divers wear "thermal protection" in, for example 75 degree water, when 75 degree air is relatively comfortable for shorts, etc.
I'm aware of most of the causes, (greater density of water vs. air, for one ) but I can't find a conversion formula, if there is one.
Thanks in advance,
Mike
