2. (12 points) The 8" sanitary sewer has an invert elevation of 7170' at the manhole,which is 200' upstream of the point of connection to the building sewer. Thesanitary sewer

maintains a slope of 1.3% from the manhole to the point of connection at point C. 1. Calculate the invert elevation of the sanitary sewer at point C. 2. Calculate the elevation of the minimum point of connection (top quadrant) of the sanitary sewer at this point.
