a) Two reservoirs are connected by a pipeline which is 150mm in diameter for the first 6m and 225mm in diameter for the remaining 15m. The entrance and exit are sharp and the change of section is sudden. The water surface in the upper reservoir is 6m above that in the lower. The friction factor, lambda for both pipes is λ = 0.04. i) Sketch the system and show the hydraulic gradient and total energy gradient. ii) Tabulate the head losses that occur, describing each loss including the coefficient of loss. iii) Calculate the rate of flow in m³/s.
