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

The density of air is 1.293 kg m^3 . Express it in cgs units.

Air stream flows horizontally past an aeroplane wing of surface area 4 m^(2) . The speed of air over the top surface is 60 ms^(-1) and under the bottom surface is 40 ms^(-1) The force of lift on the wing is (density of air = 1 kgm^(-3) )

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 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 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 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

The intensity of a plane progressive wave of frequency 1000 Hz is 10^(-10) Wm^(-2) . Given that the speed of sound is 330 m//s and density of air is 1.293 kg//m^(3) . Then the maximum change in pressure in N//m^(2) is
