Determine the increase in pressure in a pipe with a diameter d = 5 cm and a wall thickness d = 2 mm during a hydraulic shock. The flow velocity in the pipe is v = 7 m/s. Modulus of elasticity of the liquid Ezh = 2700 MPa, density of the liquid p = 900 kg/m3. The elastic modulus of the pipe material is Et = 2•105 MPa.
