CO2 Cartridge discharge thrust?
I am trying to figure out how much thrust would be created with a full discharge of a typical small CO2 cartridge. Way back when in High School we built CO2 powered drag racing cars in shop. (I can't remember how we dischardged them?). But I want to rig a similar device to discharge underwater. I want it to give a "turbo boost" to a fairly heavy model boat after the boat gets moving a bit. So it doesn't have to get the boat moving or up to a speed. It's more to give the boat a good push after it gets going.
How much thrust would that generate? In water? I could probably rig 2 cartridges to fire simultaneously on each side of the boat.
