A valve is closed in 5.5 s at the end of a 4000 m long pipe carrying oil of density 917 kg/m³
at a velocity of 2.0 m/s. Assuming the pipe to be rigid, estimate the peak pressure deve loped by this closure and the length of the pipe subjected to this peak pressure at the end of the closure time. For the oil K = 1.38 ×  10⁹
Pa.
