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.

2.2 A 250 mm diameter pipe is 1500 m long. When the discharge is 0.095 m3/s in this pipe, the pressure drop between the ends of the pipe is measured as 98.06 kPa. The elevation at the end of the pipe is 10 m below its beginning. What type of flow is this? What is the equivalent sand-grain roughness of the pipe wall? What is the Hazen-Williams roughness coefficient? How much energy is dissipated by fluid friction during each hour...

35. (a) A reservoir A discharges water to a lower reservoir B through a 3600 m long pipe of diameter 600 mm. The flow is due to gravity and the difference in surface water levels in A and B is 13 m. Reservoir A is now required to supply water also to a third reservoir C, the water surface of which is 15 m below that of A. The discharge to C is to be made from a 1200 m...
