cfm) that goes with that?<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> The DOE2-2 dictionary loves to use the phrase, "total fan power per unit flow" in defining SUPPLY-KW/FLOW. Clear as mud.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> I figured this: At design conditions, the supply fan runs at 9.90 BHP and 61.89% efficiency and the per-unit flow is at unity ( x CFM / x CFM = 1). The motor nominal
efficiency is 93%. (No, I don't have a motor efficiency curve.) 0.746 kW = 1 HP. Therefore, the fan kW = 9.90 * 0.746 / ( 0.6189 * 0.93 ) = 12.83 kW. The per unit flow is 1. So... SUPPLY-KW/FLOW = 12.83, which I type into my .inp file.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> Naturally, eQuest gives me an error message, insisting that SUPPLY-KW/FLOW must be between 0.0 and .0080. Evidently, there is some discrepancy involving units or the meaning
of "per unit" in the context of the quoted phrase.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> Can anyone clarify what eQuest really means and how to calculate SUPPLY-KW/FLOW? Is it supposed to be KW-per-CFM?</span><o:p></o:p></p>
