I saw on myth busters where they took compressed air tanks an attached them to a boat and then opened the valve and then the boat started to move. They did 2 trials, one where the exhaust nozzle was pointed above the water and one where it was pointed in the water.
Then one that was pointed above the water went faster. Is this because the air can leave at a higher speed so there is more momentum transfer?
