Your numbers are also fine.
However you are, I think, working at AirFlow=30m^3/min( 0.5m^3/s), which is 75X the AirFlow at which there is a "Measured Heat Dissipation" of ~50w ( Graph 12)
Looks GIGOish
Also not at all happy in your description of Bill's C/W.
His C/W, IMO, should be C/"Measured Heat Dissipated"
Using current practice this is, for these tests, 5/"Measured Heat Dissipated"
As can be seen from Graph 12 it decreases with increasing flow. |
Yes the units are wrong, i'm fairly sure about the other stuff. The eff seems high and i'll have to recheck my notes. It could be this high in real life as the operationg conditions are close together so entropy loses could be quite high. Notice alos how large the error bars are so this eff value even if it is right is clearly not acceptable as a good test.
