But they need a grate on that pipe.
With a grate on the pipe, the diver would not have been able to get off grate. Can’t fix stupid.
If the suction was that strong there, a grate would only guarantee the next person to dive too close would get sucked against the grate--and possibly be there long enough to run out of air.
If the guy got pulled through and survived that unhurt, the design is good.
If there was a grate he would have been pinned to it by the suction and he would have probably drowned when his air ran out.
There ain’t no cure for stupid which is why you are right they need a grate. There has always been on over the Turkey Point Power Plant near Miami. They use screens because the shrimp are attracted to the warmth. a lot of people used to shrimp near the plant.
