Question

to lift an aeroplane an uplifting force of 1800 Newton per metre square is required. Velocity of flowing below the wing is 80 metre per second. what should be the velocity of air flowing over the wings so that the aeroplane can lift vertically upwards.
density of air= 1kg/m³​

Answer 1

Answer:

The Bernoulli equation states that an increase in velocity leads to an decrease in pressure. Thus the higher the velocity of the flow, the lower the pressure. Air flowing over an airfoil will decrease in pressure. ... Lift is proportional to dynamic pressure and wing area.
