ANALYSIS ONLY A 180 reducing elbow attached to a honzontal pipe dinlet dia, 01, mm) is used to direct water flow. The diameter of e bow tapers gradually to an exit diameter of D2mm as shown in the figure Water is being freely discharged into the atmosphere through the elbow exit at rate of m(dotyka/s. The centre line of the exit elbow is situated at a helght ot, 1, mm above from the centre line of the Inlet. The mass of the elbow and the water in it can be taken as W kg. Assume the density of water as 1000 kg/m Relevant Data: Diameter of inlet pipe (D1)=200 mm Diameter of inlet pipe (D2)= 120 mm Mass flow rate 'midot) - 20 kg/ h = 1100 mm W-55kg 02 mm Reducing elbow hemm Wik Mass flow rate, kas D1, mm Not to scale Complete the following on your answer sheets) (a) Write down three (3) valid assumption.
