application in 
Dynamic lift of aeroplane: according to Bernoulli’s theorem , if the velocity is more ,pressure would be less and vice-versa. So, the air pressure on the upper surface of the aeroplane will be less than the atmospheric pressure. ]]> 2022-01-18 08:02:38 UTC https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997312019 https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997320960 As the speed of a moving fluid increases , the pressure within the fluid decreases. The total mechanical energy of the moving fluid comprising the gravitational potential energy of elevation, the energy associated with the fluid pressure and the kinetic energy of the fluid motion, remains constant. 

 Spining Ball: A ball which is spinning drags air along with it. If the surface is rough more air will be dragged. The ball is moving forward and relative to it the air is moving backwards. Therefore, the velocity of air above the ball relative to it is larger and below it is smaller. The stream lines thus get crowded above and rarified below. This difference in the velocities of air results in the pressure difference between the lower and upper faces and there is a net upward force on the ball. This dynamic lift due to spining is called Magnus effect. ]]> 2022-01-18 08:08:30 UTC https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997320960 https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997320975 Bernoulli’s principle Application:

Bernoulli’s principle states that an increase in the speed of fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid s potential energy.

Blood flow and heart attack 
Bernoulli’s principle states that the sum of potential kinetic and pressure energy per unit mass of an incompressible non viscous fluid is constant. 
The artery may get constructed due to the accumulation of plaque in its inner walls. To drive the blood through this contraction, greater pressure is placed in the activity of the heart. The speed of the flow blood is raised which lowers the pressure inside and the artery may collapse due to external pressure. The heart exerts more pressure to open the artery and let the blood flow through. As a result the blood rushes through the opening, the internal pressure drops again and a collapse repeats. This may lead to a heart attack.]]> 2022-01-18 08:08:30 UTC https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997320975 https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997323549 For the streamline flow of non-viscous and incompressible liquid the sum of kinetic energy,potential energy and pressure energy is constant.

Bernoulli's principle - In a streamline flowthe sum of pressure ,kinetic energy per unit volume, and the potential energy per unit volume remains constant.

Application - 1) working of an aeroplane.
Due to the specific shape of wings when the aeroplane runs, air passes at higher speed . This difference of air speeds above and below the wings,  with Bernoulli’s principle, creates a pressure difference.

2)When we are standing at a railway station and a train comes we tend to fall towards the train. This is because of Bernoulli’s principle as the train goes past, the velocity of air between the train and us increases. Hence, from the equation, the pressure decreases so the pressure from behind pushes us towards the train. This is based on Bernoulli’s effect]]> 2022-01-18 08:11:39 UTC https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997326576 https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997327275 Bernoulli's principle is used for studying the unsteady potential flow.

Airplanes: Due to the shape of the wing, speed of air above the wing is fast, while the speed of air below the wing is slow. This leads to a higher pressure below the wing, causing the plane to rise.]]> 2022-01-18 08:13:31 UTC https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997329754 https://padlet.com/poulomigoswami/bpwffxgwzpetm8ka/wish/1997332150 Bernoullis principle states that pressure and density are inversely proportional to each other.
