how fast would a "jet" fish have to swim to create an "aquatic" boom?
To get a sonic boom in air the "jet" must travel faster than the speed of sound in air. For air that is about 343 m/s. The "jet" fish would need to travel faster than the speed of sound in water. At 25C the speed of sound in fresh water is about 1497 m/s or about 1560 m/s in sea water but that changes with T, salinity, pressure, and amount of sediment.
Well, to create an "aquatic boom," a "jet" fish would need to swim faster than Michael Phelps on caffeine, doing the butterfly stroke, while being chased by a herd of cheetahs! In other words, it would have to swim at such an astonishing speed that fisherman would start receiving sonic booms instead of bites. It might even leave behind a trail of confused seagulls and a water ripple that makes speedboats jealous. So, grab your bathing suit and hold on tight because this fish will be breaking some serious sound waves!
To create an "aquatic" boom, a fish would need to swim at a speed faster than the speed of sound in water. The speed of sound in water is approximately 1,482 meters per second (5,105 feet per second). However, fish are not capable of swimming at such high speeds. The fastest fish, the sailfish, can only reach speeds of up to 68 miles per hour (110 kilometers per hour). So, it is not possible for a "jet" fish to swim fast enough to create an "aquatic" boom.
To determine how fast a "jet" fish would need to swim to create an "aquatic" boom, we need to understand the concept of an aquatic boom and the speed at which sound travels in water.
An aquatic boom is similar to a sonic boom that occurs when an object moves faster than the speed of sound in air. In water, sound travels at about 1,500 meters per second or roughly 4,920 feet per second.
To calculate the speed at which a "jet" fish would need to swim to create an aquatic boom, we would need to know the exact speed of sound in water that is required for an aquatic boom to occur. However, since this information is not specified, we can make an estimate based on the speed of sound in water.
Let's assume that a "jet" fish would need to swim at Mach 1 in water to create an aquatic boom. Mach 1 refers to the speed of an object moving at the same speed as sound in a particular medium. In this case, we'll consider it as the speed of sound in water.
Using the speed of sound in water (roughly 1,500 m/s or 4,920 ft/s), we can calculate the speed at which the "jet" fish would need to swim by multiplying the speed of sound by Mach 1.
If we assume Mach 1 in water:
Speed = Mach number * Speed of sound in water
Speed = 1 * 1,500 m/s
Therefore, the "jet" fish would need to swim at a speed of approximately 1,500 meters per second or around 4,920 feet per second to create an aquatic boom.
It's important to note that the speed of sound in water may vary depending on temperature, salinity, and other factors, so the exact speed required for an aquatic boom can vary. Additionally, "jet" fish do not exist in reality, so this is purely a hypothetical scenario.
