The water is flowing with a flowrate of \(\mathrm{Q}=0.5 \mathrm{~m}^{3} / \mathrm{s}\) in a pipe of length \(1900 \mathrm{~m}\), pipe diameter \(600 \mathrm{~mm}\) and pipe thickness \(16 \mathrm{~mm}\). The pipe is elastic, bulk modulus of water \(\mathrm{E}_{\mathrm{b}}=2.1 \times 10^{9} \mathrm{~N} / \mathrm{m}^{2}\), The modules of elasticity for the pipe material \(\mathrm{E}_{\mathrm{p}}=3 \mathrm{x} 10^{11} \mathrm{~N} / \mathrm{m}^{2}\). At the end of the pipe, a valve is provide. Find the rise in pressure DP and pressure DH, if the valve is closed in \(2.0\) seconds.
