An aeroplane of mass $3 imes 10^{4}$ 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 surface of its wings in kilo pascals is $(g = 10\ ms^{- 2})$

Question

An aeroplane of mass $3 	imes 10^{4}$ 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 surface of its wings in kilo pascals is $(g = 10\ ms^{- 2})$

Dr. Abubacker · Accepted Answer

(a) In level flight of aeroplane, $mg = pA$
Or $p = \frac{mg}{A} = \frac{3 	imes 10^{4} 	imes 10}{120}\ Pa = 2.5\ kPa$
