Question

On the basis of Bernoulli's principle explain lift of an aircraft wing.

How does Bernoulli's principle help in explaining vascular flutter and heart attack? ​

Answer 1

Answer:

Bernoulli's principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. ... The high air pressure underneath the wings will therefore push the aircraft up through the lower air pressure.

Bernoulli's principle states that at constant height , pressure is inversely proportional to the velocity of the fluid. Due to accumulation of plaque in artery , velocity of the blood through reduces , pressure exerted by heart is increased, this may result in heart attack.

Aerofoil : Lift of an Aircraft Wing :- Aerofoil is the name given to a solid objects have to provide an upward vertical force as it moves horizontally through air. This upward force (Dynamic Lift) makes airplanes fly. The cross section of the wing of an aeroplane looks like an aerofoil. The wing is so designed that its upper surface is more curved then the lower surface and the front edge is broader than the rear edge.

As the aircraft Moves, the air moves faster over the upper surface of the wind and on the bottom police top according to the Bernoulli's principle of the ear pressure above the upper surface decreases below the atmospheric pressure and that on the lower surface increases about the atmospheric pressure. The difference in the pressure provides an apvad lift call dynamic lift to the aircraft .

Blood Flow and Heart Attack :- In person suffering with advanced heart condition the artery gets constructed due to the accumulation of the Blake on its inner wall. in order to drive the blood through this construction a greater demand is placed on the activity of the heart. The speed of blood flow increases in this region.

From Bernoulli's principle the inside pressure drops and artery make collapse due to external pressure. The The heart exerts further pressure to open this artery and forces the blood through. The blood rushes through the opening the internal pressure once again drops leading to a repeat collapse. The Phenomenon is called Vascular Flutter which can be heard on a stethoscope. This may result in a heart attack .
