**MathMate**, Thursday, December 3, 2009 at 11:10pmUsing Bernoulli equation:

P+(1/2)ρV²+ρgh=constant.

We get

P1+(1/2)ρV1²=P2+(1/2)ρV2²

ρgh being constant.

Thus

P2-P1=(1/2)ρ(V1²-V2²)

=(1.293*g)*(302²-287²)

=111,952 N/m²

The net upward lift

=111,952*20.1 N/m² m²

=2.25*10^{6}N

Compare with the weight of a Boeing 747-8:

442,000 Kg= 4.33*10^{6}N.
