###### Question details

A circular, 60-inch diameter, reinforced concrete sewer pipe carries 50 MGD of wastewater to a lift station wet well. Average slope along the flow path is 1.0%.

(a) Sketch the cross section, indicate the pipe diameter, the water surface position, and the flow depth:

(b) For the conditions in the problem statement, what is the flow rate in cubic feet per second?

(c) Determine the depth of flow in feet.

(d) Determine the depth of flow in inches.

(e) Determine the depth of flow as a fraction of the pipe diameter.

(f) For the conditions in the problem statement, is this portion of sewer close to surcharged?

(g) For the conditions in the problem statement, what is the mean section velocity in feet per second?
