  1. a) Use Manning’s to determine the velocity of flow and the capacity of the following pipes:

    • 300mm PVC main installed at a slope of 3%

    • 375mm PVC main installed at a slope of 3%

    • 450mm PVC main installed at a slope of 3%

  2. b) Comment on the percent increase in capacity when changing pipe to a larger size in the previous question. (You will have an answer for 300mm to 375mm and an answer for 375mm to 450mm. Your answer should be a % difference)

While studying "flow through pipes" we say that "as area of cross section decreases then velocity increases in turn pressure gets 'decreased'.( that is pressure and velocity are inversely proportional).However while studying "Hagen poiseuilli equation", we say "pressure and velocity has linear relation and "directly proportional" to each other. Why two different statements,? please help me to understand it.(Fluid mechanics)

Poiseuille flow describes laminar flow in a circular pipe. The velocity distribution in such flow has a parabolic form. Prove that the mean velocity is equal to one-half of the maximum velocity in this type of flow. Be sure to show all of your work. (Hint: the analysis is similar to that done for laminar flow between parallel plates)
