    "data": {
        "note": "The pressure wave travels at a = √(K/ρ) in a perfectly rigid pipe (≈1,480 m/s for water), but a real elastic pipe slows it: a = √(K/ρ) ÷ √(1 + (K·D)/(E·t)), where K is the fluid bulk modulus, E the pipe's elastic modulus and D/t the diameter-to-wall ratio. A thin or flexible (plastic) pipe gives a much lower wave speed and so a gentler surge — one reason PVC tolerates hammer better than steel.",
