Micro Python - Calculate speed of sound with temperature and humidity

-

Raspberry Pi Pico
Below will allow you to create accurate speed of sound calculations taking into consideration temperature and humidity in micro python.

Tested on a Raspberry Pi Pico W.


The results of the code below is not quite exact, but its pretty close.




MICRO PYTHON CODE:

from math import sqrt


def speed_of_sound(temperature, humidity):

    c = 331.3 * sqrt(1 + (temperature/273.15)) + 0.606 * temperature * sqrt(humidity/100) - 5.6 * (1 - humidity/100)

    return c


# Example usage

temperature = 10.0 # in degrees Celsius

humidity = 90.0 # as a percentage


speed = speed_of_sound(temperature, humidity)

print("The speed of sound in air at {0}°C and {1}% humidity is {2:.2f} m/s".format(temperature, humidity, speed))

One of the standout features of this keyboard is its higher keycaps, which can take some time to get used to, but once you do, you'll love the comfortable typing experience it provides. The higher keycaps allow for a more natural and ergonomic hand placement, which can help reduce fatigue during extended typing sessions. Another great thing about the e-yooso z-88 keyboard is its build quality. It is a sturdy and durable keyboard that can withstand heavy usage without showing any signs of wear and tear. The compact design also makes it a great option for those with limited desk space. Overall, if you're looking for a...

There is enough mass in the chipper drum to take a finger off. Viking GB455 Flail Mulcher Chipper with side chute Below you can see the blade for larger sticks and branches. Tools Needed (with amazon links) Socket Set Spanner Set 10mm 13mm 16mm 17mm Allen Key Set Whetstone 180 Grit WD-40 Process Firstly I unplugged the spark plug and then took off the hopper off, I did this buy removing four bolts at the base. I then had to dig out some of the chips from the allen key bolt heads. I was then able to get the 10mm socket onto the inside of the bolt, holding it in place with the Allen key while being very careful not to put my fingers or hands anywhere that the chipper barrel would...
