  • Question about steel plates.

    From JF Mezei@21:1/5 to All on Thu May 11 10:30:49 2023
    Melon will put a 2 layer steel floor below the OLM, and the top layer
    will have perforations to let water flow up like a shower head.

    Would it be correct to state that the water would need to be at slightly
    higher PSI than the pressiure exerted by the thrust of engines onto the
    steel plates in order for water to flow out of the holes? If the water
    is at insufficient pressure, it is the thrust exhaust that would flow
    into the holes and push water back up to the pumps/tanks?

    Considering the gazillions pounds of thrust generated by 33 Raptors, is
    the PSI needed to push water up against thrust realistic?

    Can such pressure be achieved with pumps? Or need to store water into
    high pressure tank with liquid nitrogen to pressurize it?

    If you have such high pressure inside the steel "floor" to ensure water
    can counter pressure from engine thrust, is there a danger the steel
    plates will simply come apart?

    I'm no mechanical or structural engineer, but steel has a very high
    tensile strength.

    Also, a fresh set of high pressure tanks has been spotted near the
    launch site.
