Question

b) For two manholes 1000 m apart, the ground elevations are 87 m and 89.5 m respectively. Given that the present peak rate of sewage flow is

7.08310^(-3)m^(3)sec

and it is estimated to go up to

1.7\times 10^(-2)m^(3)sec

at the end of 15 years design period. Under

(3)/(5)

full condition and manning coefficient

=0.015

, determine the required i. Critical slope of the area for the site ii. Design diameter for the sewer pipe (4 Marks) iii. Does the critical slope meet the minimum velocity requirement? (4 Marks) iv. Clearly explain why there is to maintain a minimum velocity criterion in (iii) above? iv. Cl (4 Marks)
