It very much depends on the size of the hole. 7 psi over 1 square inch is 7 lbs, but the same pressure over 100 square inches is 700 lbs.
For a naive estimate, the hole looks around 6 inches wide, which gives it an area of around 30 square inches, so there’s like 200 lbs of water pressure over the area of the hole. An even more naive assumption is that if you were “standing” over the hole in the wall, you would feel 200 lbs of pressure forcing you “down,” which I think most people could easily handle. I’m doing more than that right now!
Unfortunately I don’t know how to even start to calculate the force of the water on you as it rushes past you, but my gut instinct is that it wouldn’t be more than the total pressure in the hole
