			<description><![CDATA[I’m trying to size a centrifugal pump for a closed-loop cooling system, but I keep getting stuck on the system curve calculation. My theoretical head requirement seems way too high compared to the actual pressure drop I measured in my test loop, even after accounting for all the fittings and pipe length. I’m wondering if my assumption about the fluid’s specific gravity is throwing things off, or if I’m misapplying the Darcy-Weisbach equation somewhere.]]></description>
