360826 A fully loaded boeing aircraft has a mass \(5.4 \times {10^5}\;kg\). Its total wing area is \(500\;{m^2}\). It is in level flight with a speed of \(1080\;km/h\). If the density of air \(\rho\) is \(1.2\;kg\;{m^{ - 3}}\), the fractional increase in the speed of the air on the upper surface of the wing relative to the lower surface in percentage will be \(\left( {g = 10\;m/{s^2}} \right)\)

360827 Air is streaming past a horizontal aeroplane wing such that its speed is \(120\;m{s^{ - 1}}\) over the upper surface and \(90\;m{s^{ - 1}}\) at the lower surface. If the density of air is \(1.3\,kg{m^{ - 3}}\), what will be the gross lift on the wing ? If the wing is \(10\;m\) long and has an average width of \(2\;m,\)

360828 Statement A :
Aeroplanes are made to run on the runway before taking off, so that they achieve the necessary lift.
Statement B :
This is based on Pascal's law.

360829 A rectangular vessel when full of water, takes \(10 \mathrm{~min}\) to be emptied through an orifice in its bottom. How much time will it take to be emptied when half filled with water?
