A branching pipe connects two storage tanks as shown in FigureQ3 below. Figure Q3
(a) Write down the continuity equation as it applies to flows inthe pipes 1, 2 and 3. [1 mark]
(b) Write down the energy equation in terms of energy heads at Aand at B and quantities relating to flow in the pipes in between.[2 marks]
(c) What can be said about the energy loss in pipe 2 relative tothat in pipe 3? [2 marks]
(d) Using the dimensions in Table Q3 below calculate the flowrate between the two reservoirs. Iteration for more refined valuesof ï¬ is not required. [15 marks]
