An aeroplane of mass `3xx10^(4)kg` and total wing area of 120 `m^(2)` is in a level flight at some height the difference in pressure between the upper and lower surfaces of its wings in kilo pascal is `(g=10m//s^(2))`

A fully loaded Boeing aircraft has a mass of 3.3xx10^(5) kg . Its total wing area is 500 m^(2) . It is in level flight with a speed of 960 km//h . (a) Estimate the pressure difference between the lower and upper surfaces of the wings (b) Estimate the fracitional increases in the speed of the air on the upper surfaces of the wing relative to the lower surface. The density of air is 1.2 kg//m^(3) .

A fully loaded Boeing aircraft 747 has a mass of 33xx 10^5 kg . Its total wing area is 500 m^2 . It is in level flight with a speed of 960 km/h. Estimate the pressure difference between the lower and upper surfaces of the wings.

Air of density 1.2kg 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 ms^(-1) and 100 ms ^(-1), respectively. The pressure difference between the upper and lower sides of the wings, is :

An aeroplane of mass 5000 kg is flying at an altitude of 3 km. if the area of the wings is 50m^(2) and pressure at the lower surface of wings is 0.6xx10^(5)Pa , the pressure on the upper surface of wings is (in pascal) (g=10ms^(-2))

An aircraft of mass 4 xx 10^(5)kg with total wing area 500m^(2) in level flight at a speed of 720 km h^(-1) . The density of a at its height is 1.2 kgm^(-3) . The fractional increases in the speed of the air on the upper surface of its wings relative to the lower surface is (take g = 10 ms^(-2) )

A metal cuboid of mass M kg rests on a table surface area of 40cm^2 is in contact with the table the pressure exerted by the cuboid on the table surface is 10000Pa value of M is (given that,g= 10ms^-2 )

A plane is in level flight at constant speed and each of its two wings has an area of 25 m^(2) . If the speed of the air on the upper and lower surfaces of the wing are 270 km h^(-1) respectively, then the mass of the plane is (Take the density of the air =1 kg m^(-3) )

A plane is in level fight at constant speed and each of two wings has an area of 25m^(2) . If the speed of the air on the upper and lower surfaces of the wing are 270kmh^(-1) and 234 kmh^(-1) respectively, then the mass of the plane is (take the density of the air = 1kg m^(-3) )
