1. his die has less insulation resulting in greater secondary losses
2. as I understand his setup; while the die pedestal is in contact with the wb, the whole of the heat die body is in close proximity to the wb bp and its top surface uninsulated
- but this should increase the actual heat picked up by the wb
and if so will shift the die temp down a bit
-> but it is also quite possible that where he is reading the die temp may be yielding a lower temp than with my setup ???
3. none of this will be too clear until Joe has posted 3 or 4 wbs that I also tested
the shame is that Joe is going to put up only the "C/W" at 1gpm

1. Hopefully pHaestus's set-up will be able to monitor this with his accurate inlet/outlet temps.
2 Have not considered either of these.Further thought required on leakage from Shoulders of die to wb. However,would think, the effect of die probe position can lumped with "C/W(TIM)" as far as scaling with die-size.
3. Think I would put it stronger - data at other flow rates may be vital to rationalise the observations
