 Paul, here's my attempt

Area of Plate = 6x8 =48 sq inches
Volume = 6x8x.0.040 = 1.92 Cubic Inches
Weight = (Density  of Aluminum Lb/Cubic Inch)*Volume
Density Alum = .097566 lb/In^3
Weight of Plate = 1.92x.097566 = 0.187 lbs
Area of plate Ft^2= 48/144 = 0.3333 Ft^2
Dynamic force of air at 0 alt, 59 degF
that equals 0.187 lbs exerted over .3333 Ft^2

Airspeed = 21.728 ft/sec or 14.8 MPH

This aluminum plate floats all over the back side of this
radiator with a K&M diffuser. The plate is six by eight inches
and is .040 thick. Your home work assignment  is to calculate the
air speed exiting the radiator. I want to see all intermediate
calculations. The home work assignment is due by Tues morning.

Right on Ed and nice work. Unfortunately Jeff was faster.

What? You mean no prize for second place????

Vance has thrown a monkey wrench into the contest. We will have
to wait and see his sketch.
