It can use both, go on file -> configuration to change the units

Does this look right for a modified 1 inch sprinkler valve?
I'm getting very odd results using the optimization tool (such as a 1 inch chamber to 100 inch barrel).

This weapon serves to silence the noisy speakers of the stupid of the other street! (joke) -Hectmarr
I'm going to hazard a guess that the diaphragm in a sprinkler valve doesn't weigh nearly a pound and a half...
Personally, I don't think GGDT's optimiser is fantastically useful, except in fixed overall length mode (maybe). It's perhaps an interesting lesson in efficiency, but trying to eke every last joule of muzzle energy out of the compressed air leads to launchers that are highly size inefficient.
It's like vehicles from the Shell Eco-marathon, where they try to do thousands of miles on a gallon of fuel. Technically interesting, but wildly impractical for every day use.

Does that thing kinda look like a big cat to you?

That should be 22g (grams) not 22oz (= 620 grams)Cthulhu wrote:Does this look right for a modified 1 inch sprinkler valve?

Hi guys,
I finally tried GGDT and it is really useful tool. If nothing else I was able to calculate the drag coefficient of my shots based on that
Is there a way to calculate the velocity at a distance? Like I would like to calculate a velocity drop after 50 meters, can I do that inside the tool? Or is there any online calculator capable of doing that universally? So far I have found only a simple ones or those suitable for rifles and bullets only.
Thanks

Download Chairgun, it's very good once you understand how to navigate it.Is there a way to calculate the velocity at a distance? Like I would like to calculate a velocity drop after 50 meters, can I do that inside the tool?

Here's an example of data generated to compare two different pellet shapes with all other criteria being equal:
