360818 Air flows horizontally with a speed \(v = 108\;km/hr\). A house has a plane roof of area \(A = 20\;{m^2}\). Find the magnitude of aerodynamic lift on the roof \(\left( {{\rho _{air{\text{ }}}} = 1.26Kg/{m^3}} \right)\)

1 \(1.13\,kN\)
2 \(11.3\,kN\)

360820 The dynamic lift of an aeroplane is based on

1 Torricellii's theorem
2 Bernoulli's theorem
3 Conservation of angular Momentum
4 Principle of continuity
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

360821 Air is streaming past a horizontal aeroplane wing such that its speed is \(120\;\,m/s\) over the upper surface and \(90\;\,m/s\) at the lower surface. If the density of air is \(1.3\;\,kg/{m^3}\), then the difference of the pressure on the two sides of the wing is :-

1 \(409.5\,\;N/{m^2}\)
2 \(40950\,\;N/{m^2}\)
3 \(4095\,\;N/{m^2}\)
4 \(40.95\,\;N/{m^2}\)
