I was supposed to be looking up something else entirely, but when I saw the “Darcy friction factor” in the index, I couldn’t resist. Even better, it is the Moody Darcy friction factor. I think this calls for a detailed experimental study to determine Moody Mr. Darcy’s friction factor, and I heartily volunteer to participate.  I’d like to tap into a little of Moody Mr. Darcy’s latent heat, if you know what I’m saying.  I’d like to transfer a little heat between us by means of conduction.  I’d like to put his working body against my hot body in a Carnot cycle of love.  Alright, that’s enough.
