d= 0.01m P-100 kPa pin=300 kPa ain Q1 3) a, a2 a2 D= 0.02m P4-100 kPa For the pipe system above, assume that the big pipe has a diameter of 0.02m and the small pipes have a diameter of 0.01 m. Consider now that flow with a magnitude of Qin= 0.01 m,s is split into two smaller flows, each with the same magnitude flow rate (i.e.e). The pressure because the velocity speeds up drops by 200 kPa as a result of turbulence in the flow and i. ii. iii. What is Qi? What is the velocity, vi? Is energy conserved? Outline (with an equation) how you would determine whether energy is conserved or not as one follows a streamline from the big to small pipe. Extra credit: described in the flow? Justify with plugging numbers into an equation. Is energy conserved, or must there be a source or sink of energy iv.
