A liquid flowing from a reservoir thru a non-rigid 600 mm diameter pipe with a velocity of 2.5 m/s is completely stopped by a closure of a valve situated 400 m from the reservoir. Assume that the pressure increases at a uniform rate and there is no damping of the pressure wave. The pipe has a thickness of 20 mm and its modulus of elasticity is 1.4 x 1011 Pa. The liquid is pre-tested to determine its bulk modulus of elasticity. The liquid is compressed in a cylinder at a volume of 1000 cubic meters at 230 MPa and a volume of 990 cubic meters at 250 MPa. Assuming liquid density is 950 kg/m3, compute the water hammer pressure if the valve was closed in 0.9 seconds.
