) A particulat aircraft design calls for a
lift of about 1.2 x 10'N on each
square metre of the wing when the
speed of the aircraft through the air
is 100 ms-. Assuming that the air
flows past the wing with streamline
flaw and the flow past the lower
surface is equal to the speed of the
aircraft, what is the required speed
of the air over the upper surface of
the wing? (Density of "air
1.3 kgm-.)
