Course name hydraulicsThe 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...

Q2 A 200 mm diameter cast iron pipe with wall thickness of 15 mm is carrying water when the outlet is suddenly closed. Calculate the maximmum discharge if the pressure rise is not to exceed 180 kN/m2 (a) assuming the pipe is rigid; (b) allowing for hoop stress but not longitudinal stress in the pipe wall; (c) assuming the pipe to have expansion joints throughout its length.

The length of a 20 cm rigid pipe carrying 0.15 m3/s of water (at 10°C) is estimated by instantaneously closing a valve at the downstream end and noting the time required for the pressure fluctuation to complete a full cycle (all 4 strokes). If the time interval is 6 s, what is the pipe length?
