Question

You are designing a new 27-inch VCP (vitrified clay pipe) sanitary sewer to convey a peak flow rate of12 cfs. The peaking factor (ratio of peak to average flow rate) is 2.5. Calculate the minimum acceptable slope for this sewer Show with calculations whether both peak and average flow rate will be subcritical, critical orsupercritical Based on class discussion of LACSD sewer rehabilitation, state the most likely rehabilitationmethod for this sewer in the future
