14.14 A cast iron pipe (E = 1.0 × 10¹¹ Pa) is 0.9 m in diameter and carries water (K=2.0 x 10⁹ Pa) at a velocity of 2.60 m/s. A valve in this pipe is instantaneously closed bringing the flow to a sudden stop at the valve end. Estimate the water hammer head produced due to this action. The pipe thickness is 1.25 cm and the pipe can be treated as elastic. Solution: The velocity of pressure wave 1/2 1 C=√√Klp 1+ (D/t) (K/E)
