Air is streaming past a horizontal airplane wing such that its speed is 120 metre per sec over the upper surface and 90 metre per sec at the lowers surface. If the density of air is 1.3 kg per `metre^(3)` and the wing is 10 metre long and has an average width of 2 metre, then the difference of the pressure on the two sides of the wing is :

Air is streaming past a horizontal air plane wing such that its speed in 120m//s over the upward surface and 90m//s at the lower surface . If the density of air is 1.3kg//m^(3) and the wing is 10 m long and has an average width of 2m , then the difference of the pressure on the two sides of the wing of ...... Pascal .

Air is streaming past a horizontal air plane wing such that its speed is 120 ms^-1 over the upper surface and 90 ms^-1 at the lower surface. If the density of air is 1.3 kg m^-3 m find the difference in pressure between the top and bottom of the wing. If the wing is 10 m long and has an average width of 2 m , calculate the gross lift of the wing.

Air is streaming past a horizontal airplane wing such that its speed is 90 ms^(-1) at the lower surface and 120 ms^(-1) over the upper surface. if the wing is 10 m long and has an average width of 2 m , the difference of pressure on the two sides and the gross lift on the wing respectively, are (density of air =1.3kgm^(-3) )

Air is streaming past a horizontal aeroplane wing such that the speed of air is 120 m/s over the upper surface and 90 m/s at the lower surface, with respect to the plane. If the density of air is 1.3kg/ m^(3) , find the difference in pressure between the top and bottom of the wing. If the wing is 10m long and has an average width of 2m, calculate the gross lift of the wing.

Air is streaming pasta horizontal airplane wing such that its speed is 90 m at the lower surface and 120 ms^(-1) over the upper surface. lithe wing is 10 m long and has an average width of 2 m , the difference of pressure on the two sides and the gross lift on the wing respectively, are (density of air =1.3kgm^(-3) )

Air streams horizontally past an air plane. The speed over the top surface is 60 m/s, and that under the bottom surface is 45 m/s. The density of air is 1.293 kg/ m^(3) , then the difference in pressure

Air streams horizontally past an air plane. The speed over the top surface is 60 m/s, and that under the bottom surface is 45 m/s. The density of air is 1.293 kg/ m^(3) , then the difference in pressure

Air is blowing across the horizontal wings of an aeroplane in such a way that its speeds below and above the wings are 80 m/s and 120 m/s respectively. If the density of air is 1.2 kg/m^3 then the pressure difference between the lower and the upper sides of the wings will be
