Using the Manning nomograph and assuming n=0.013, determine the following:
(a) An 800 mm diameter sanitary sewer is built on a slope of 0.2 percent. What is the fullflow discharge capacity of the sewer and what is the flow velocity?
(b) What diameter pipe is needed to carry a peak flow of 200 liters/s on a grade of 0.007 ?
(c) A 300 mm diameter sewer is built at a grade of 2 percent. What is the depth of sewage flowing in the pipe when it carries a flow of 50 liters/s? What is the velocity?
USE MANNING MONOGRAPH, NOT HAZEN WILLIAMS
