On top of that, he is in an area where the density of air is quite small. In fact, he is a small object high above the ground so it would be hard to hear.
Speed of sound in fps windows#
There should be one, but it wouldn't break any windows or anything. Honestly, I am not sure of the exact answer. Image: Wikipediaīut I still haven't said if there was a sonic boom for Felix as he fell.
Speed of sound in fps driver#
At the flick of a switch, they shoot off the sides, with the driver or an Xbox-loving patrol officer at home base controlling the mono-wheeled UAV as it slices through traffic in hot pursuit.Ī Flying Pursuit Unit (or FPU – let's just call it a drone), deploys from the nose of the E-Patrol, equipped with a pair of video cameras, a 3D terrain scanner and radar which autonomously flies over traffic to scout out what's causing yet another massive backup on the 405. It looks like the mashup of two Tron Lightcycles stitched together with an AMOLED/carbon fiber roof, but those two massive rear wheel arches are actually single-wheeled drones that are magnetically attached to the body. Dick to create the E-Patrol Human-Drone Pursuit Vehicle. It's as if BMW's Southern California design studio channeled the unholy lovechild of William Gibson and Phillip K. Engineering Physics Speed of Sound table chart including Speed of Sound at a known temperature and density of air, Speed of Sound vs Density of Air.
Here is a plot of the speed of Felix as a function of altitude in terms of the Mach number (again, this is based on my not so perfect model). It has the definition of Mach number as the ratio of the speed of an object to the local speed of sound. I guess I was right ( at least according to Wikipedia). You should also notice that this calculation has his maximum speed a little over the reported value of 373 m/s - hopefully I can fix this later when I compare my model to the real data - but it's not too far off. You will notice that from this numerical calculation, Felix was going faster than the local speed of sound for about 45 seconds. Here is a plot of the speed of Felix as he falls along with the plot of the local speed of sound at that same time. I am using it to mean the speed of sound at the current altitude. I don't know if "local speed of sound" is an official term, but I like it. Was he also going faster than the speed of sound for the altitude he was at? Well, it makes logical sense that if the speed of sound is greatest at sea level and he went faster than the speed of sound he would be going faster than the locals speed of sound. The speed of sound depends on several variables, but the only independent variable we need to calculate the speed of sound is the temperature of the air. Did he fall faster than the speed of sound at sea level? Yes.
Apparently, the higher the pitch, the faster the speed of sound. The second factor that affects a sound waves speed is pitch. For example, sound travels approximately 4.3 times faster through water than air. However, the question doesn't really make sense. What effects the speed of sound other than temperature and viscosity, is the thickness of the medium its traveling through. Just from this data, you can see that Felix Baumgartner did indeed fall faster than the speed of sound. If you move up to 120,000 feet, the speed will drop down to around 200 m/s. Table showing various speed of sound measurements converted to feet per second.At sea level, the value is right around the 340 m/s mark. Speed of Sound to Foot per Second Conversion Table The velocity in feet per second is equal to the distance in feet divided by time in seconds. For example, ft/s is expressing a change in length or distance relative to a change in time.įeet per second can be expressed using the formula: In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units. For example, 1 foot per second can be written as 1 ft/s, 1 ft/sec, or 1 fps. In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities. Feet per second can be abbreviated as ft/s, and are also sometimes abbreviated as ft/sec or fps. In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). The foot per second is a US customary and imperial unit of speed. Feet per second are a measurement of speed expressing the distance traveled in feet in one second.
