No need for chapter and verse type level ... at least not for me ... Just a point in the direction should give me what I am looking for.

I'll take a look... thanks for the point.

That would be the obvious 1st issue I have with that chart.
The Second thing I noticed is that ... that graph looks to contradict what mort was expecting ...
- That Graph looks like it shows the coolant load being a significantly larger % of the energy content of the fuel than the Exhaust is for a large part of the graph ... the graph is showing the coolant system being over 50% of the energy content of the fuel on the left hand side ... way above the 30% max mort suggested as a upper limit.
- That graph shows on the left side more than 250% of the drive shaft power going to the coolant system ... way above the 175% mort found to be incredible... and way above his worst case of 100%.
But to be fair ... I do not know the context of the graph.
