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%
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)
