I found out that the upper hose is the inlet but depends on if your talking about the heater core or intake manifold.
Inlet - Engine to Heater upper hose at heater

..
You could turn on the heater to the max and feel which hose
is the hottest.
In the old days I have reversed the hoses while doing a
coolant flush to clear any crud that may have been in the
heater core.
I once read that there was an engine that used the flow of
the heater system to help cool a part of the engine.
Have a good one.. Don S..
