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 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 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 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 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.
