Air of density $1.2\mathrm{kg}{\mathrm{m}}^{-3}$ is blowing across the horizontal wings of an aeroplane in such a way that its speeds above and below the wings are $150{\mathrm{ms}}^{-1}$ and $100{\mathrm{ms}}^{-1}$, respectively. The pressure difference between the upper and lower sides of the wings, is :
