Because the fluid velocity is the unknown I'm looking for, I've been using Pr and Nu to find Re with excel solver. The heat transfer coefficient I've been comming up with has been between 50 and 100,000. My Pr has been about 6.36, which is reasonable, but Nu has been all over the place. Re...
I am trying to optimize a quench tank for large steel castings (hardnesses aren't uniform throughout batches). Because the flow is randomly directed, we had some spherical copper probes made with heaters and thermocouples inside to get a better idea of the different flow rates throughout the...
Hi, I'm having a difficult time with what should be a simple problem:
I'm trying to find a fluid velocity using a cooling rate of a copper sphere following a lumped capacity model. I have all the correct units and thermodynamic properties; and I believe I have all the correct equations. I keep...
