well, I gave Steve something to chew on in
this post
we shall see
but the response from 'the kiddies' has been predictable;
whatever technical criticisms one may have about the article, it sure was effective for their audience

I neglected to answer your water temp question
inlet and outlet is not useful as it will reflect the applied heat load
(i.e. the same for all wbs at that load)
what is most necessary is the wb inlet temp as that is the basis for wb comparisons
and the resolution and accuracy of this measurement will define everything else you do
EDIT: an addendum to the wb coolant inlet temp 'importance'
the problem you will encounter is maintaining the inlet at a constant 'set point'
the desireability of such is to enable the comparison of test results without numerous corrections, offsets, adjustments, etc
and its not so easy to hold the inlet temp constant even over the duration of a single test
forget not -> steady state conditions
