Friction In Pipe In this experiment, you are required to measure the left and right levels (limb reading) of the manometer. Apparently, the right side is higher than the left. In your own words, explain what has actually been measured? What do you think about the water flow rates inside the pipe and at the exit valve? Is it less, the same or higher? Justify your answer.
