lets have a shift here as this is my intended audience

1) when a fan is mounted with a shroud it is possible to get a plenum pressure indicating roughly where that specific match-up falls on that fan's PQ curve (w/unconfined/unconstrained discharge)
- anyone have an 'experimental' feel as to how shallow the shroud might be before the pressure was non-uniform (otherwise assumed)
- pitot tube considerations ? (airspeed too low to matter ?)

2) if it is accepted that the fan inlet air temp is reasonably characterized by TC msmt in each quadrant over the fan mid-blade (the Intel procedure), would the same be true for the fan/rad discharge ?
- with some other factoids could calc mass/vol air flow ?
