A steel pipe, 3.5 km long x 80 cm diameter x 1 cm wall thickness, conveys water at the rate of 1.75 m3/s. Determine the increase in pressure when a valve provided at the downstream end of the pipe is closed instantaneously. Consider pipe to be elastic and take bulk modulus of water K = 2x109 N/m2; Modulus of elasticity of steel E = 2x1011 N/m2. After determining the surge of pressure in the pipe, compute the following: A) The Longitudinal Stress of the Pipe in Pascal. B) The Circumferential Stress of the Pipe in Pascal.
