What is the optimal barrel length for my launcher?
Although there are many variables that affect optimal barrel length, a good rule of thumb suggests using a barrel about the same length as the pressure chamber if they have the same diameter. However, near-optimal ranges can be achieved with longer barrels and shorter pressure chambers – often nearing a 2:1 or even 3:1 ratio. In water wars, having such a ratio is optimal because incredible ranges are useless and because practicality calls for less air used per unit of distance.
