<p> <o:p></o:p></p>
<p class="MsoNormal">I have a situation where I want to estimate the seasonal <u>
variance</u> in the potable domestic water supply as a function of atmospheric drybulb temperatures. I *think* eQuest has some algorithm to derive 12 (monthly average) temperatures from the weather file data for makeup/DHW purposes… however after scanning
the 2.1e engineers manual and a first pass at trying to find some helpful entry in the resource manual, I’m coming up dry so far.

<p class="MsoNormal">I’m trying hoping to source the equations & assumptions used for this estimation, so that I can modify it to fit my project. I’m not specifically married to matching eQuest’s output – any similar process/formulae would be welcome.
