Bernoulli's principle is basically an idea of fluid dynamics. This describes that as the speed of the fluid increases, pressure decreases. This principle includes both the work by the pressure and by the changes in potential energy from changes in height.
Below are the common applications of Bernoulli's principle.
One of the most common everyday applications of Bernoulli's principle is in airflight. It works in the air flight has to do with the architecture of the wings of the plane. Wings top part is curved and the bottom of the wing is totally flat. Air flows across both the top and the bottom concurrently. This allows for the air on the bottom to move slower, which creates more pressure on the bottom, and allows for the air on the top to move faster, which creates less pressure. Due to which it creates lift, which allows planes to fly.
Baseball is a good example you see in everyday life. Baseball is in the shape of a curveball. The ball is spinning in a certain manner, this allows more air pressure on the top of the surface and less air pressure on its bottom surface. Therefore, according to the principle, there should be less speed on the top of the ball than there is on the bottom of the ball, which causes the batter to miscalculate the ball's position.
This principle also works for creating lift in the sail boats. The sailboats have two parts, a sail which points north and a keel which points in the opposite direction. If the speed of the air increases on the sail then there will be less pressure on the sail and less pressure on the keel, this produces lift and propels the sail to move in the water.
