Hi,
I have a set of engine run data for 4 engines. Different engines are on at
different times and I want to know a common value, say the blended oil temp
if they all share a common oil loop. I've figured there are 15 non repeating
combinations and for each combination there is a different oil temp. How
could I go about determining what my oil temp will be based on which engines
are on for the data given?

Thanks
