Characteristics of turbulent flow are: Re > 4000 'high' velocity Dye mixes rapidly and completely Particle paths completely irregular Average motion is in the direction of the flow Mathematical analysis very difficult  so experimental measures are used Most common type of flow. Q 2 . What is head loss due to friction in the following pipe? The head loss in the given pipe due to friction can be expressed as: h = fLv 2 2gd Or h = h 2 – h 1 According to the experimental data the following values were calculated for head loss: MANOMTER h 1 (m) MANOMTER h 2 (m) HEAD LOSS h (m) FOR HIGH PRESSURE: 0.190 0.175 0.015 0.200 0.165 0.035 0.210 0.155 0.055 0.220 0.145 0.075 FOR LOW PRESSURE: 0.205 0.165 0.040 0.215 0.150 0.065 0.225 0.140 0.085 0.235 0.130 0.105...
