4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...

Water flows at a rate of 22 L/min through a horizontal 7.0-cm-diameter pipe under a pressure of 17.0 Pa . At one point, calcium deposits reduce the cross-sectional area of the pipe to 21 cm2 . What is the pressure at this point? (Consider the water to be an ideal fluid.) Express your answer using two significant figures.
