One day in the autumn of 1912, when the world’s largest ocean-going wheel, the Olympics, was sailing on the sea, a 100-meter-long ironclad cruiser, the Howe, was running in parallel. Suddenly, the unexpected happened. The “Hooker” seemed to be attracted by the tremendous force and rushed to the “Olympic”. As a result, the “Olympic” ship’s ship was hit by a big hole.
What power is driving the two ships to collide? When the liquid flows, the internal pressure is related to the flow rate, the pressure is small in the place where the flow rate is large, and the pressure is strong in the place where the flow rate is small. When the two ships are moving forward in parallel, the water between the two ships flows faster than the water outside, resulting in the water pressure between the two ships being much smaller than the water outside the ship. The seawater on the outside of the ship generates a huge thrust on the ship’s side, making The two boats approached and collided.
Gas is also a fluid and has the same properties. The fast-moving train creates a strong airflow around the cabin that attracts objects next to it. When the train travels at a speed of 50 kilometers per hour, it will generate a lot of pressure. Therefore, people should stay away from the rails when the train is coming, otherwise it will be prone to casualties.
