    "data": {
        "note": "The critical time = 2L/a, the round-trip time for the pressure wave to travel to the far end of the pipe and back. Close the valve faster than this and you get the full Joukowsky surge; close it slower and the returning relief wave eats into the rise, so the surge falls roughly in proportion. Sizing valve-closure times (or fitting a surge tank/air chamber) above the critical time is the standard way to tame water hammer.",
