Problem # 1 For the simple pipe system shown in the figure, the pressure are p1=14 kPa, p2=12.5 kPa, and p3=10kPa. Determine the head loss between 1 and 2 and the head loss between 1 and 3. The discharge is 7 l/s. The energy equation between 1 and 2 is: 2 1 L 2 2 2 2 1 2 1 1 h z g 2 V p z g 2 V p + + + = + + γ γ g 2 V g 2 V 2 2 2 1 = Where and z 1 =z 2 2 1 L 2 1 h p p + = γ γ m 153 . 0 m kN 79 . 9 kPa 5 . 12 kPa 14 p p h 3 2 1 2 1 L = = = γ
