The graphic below shows a reducing section that is part of a vertical pipeline. The pipeline contains an oil (S = 0.8) that is flowing at a rate of 0.6 m³/s. The pressure at the entrance to the reducing section (i.e. the larger diameter section indicated as point 1) is p₁= 200 kPa. The dimensions of the section are: L= 450 mm, D₁= 450 mm and D₂= 300 mm. Assume the temperature as 5°C. Ľ. X P₁ D₂ D₁ Q (2 Determine the force on the reducing section. In your calculations you should neglect losses but include gravity. Draw appropriate diagrams to support your working out. Magnitude of the force: L 1
