Handliston A steel penstock 500 mm in diameter has shell thickness of 10 mm. The modulus of elasticity of the shell material is 2.0 x 105 N/mm2 & the bulk modulus of elasticity of water is 2.0 x 103 N/mm2. The pipe is designed to discharge water at a mean velocity of 2.0 m/sec. Determine the pressure rise caused by the sudden closure of a valve at the downstream end by neglecting the elasticity of the pipe material.
