I've been arguing with my dad about whether drilling a 2nd hole on our PVC water gun (which has 1 hole) would reduce the velocity of the water coming out.
He thinks that 2 holes will halve the velocity of the water.
I think that when putting the same energy into the gun, it will shoot the same as the 1-holed variant we have now because more energy will be put into the water moving, instead of being held up against the walls of the gun.
Think of it this way, a crowd of people is moving out of a theater. There are 100 They are going towards 1 door, they move at the same speed, but they're kinda stuck, and the people moving out of the room is 10 people/s
Now, a week later the managers of the theater make a second exit. The people travel at the same speed, with the same energy, there's still 100, but they're less stuck and now they move out of the room at 20 people/s
So, will the water leave at the same velocity with a 2-holed gun?
(BTW is this the appropriate forum? The Space math/physics forum is for space math and physics, and I don't think waterguns are space physics )
