Solution:

Minimum flows in sewers is needed to maintain minimum flow velocity or self cleansing velocity to avoid siItation problem.

QUESTION: 5

The ratio of maximum daily sewage flow to the average daily sewage flow for sewer mains of 0.5 to 1 m diameter, is generally taken as

Solution:

Maximum daily flow = 2 times the average daily flow
Maximum hourly flow =1.5 times the maximum daily flow
= 3 times the average daily flow

QUESTION: 6

The ratio of minimum hourly flow to the average flow of sewage, is

Solution:

Minimum daily flow = 2/3 x Average daily
Minimum hourly flow  = 1/2 x Minimum daily flow 
= 1/3 Average daily

QUESTION: 7

The value of the coefficient of runoff for perfectly impervious areas, tend to:

Solution:

Coefficient of runoff is a factor which tells the proportion of water flowing off and not going into the earth. Since, for perfectly impervious area all of the water will flow off and none will get into the ground, therefore, the coefficient of runoff will be equal to 1.

QUESTION: 8

The drainage discharge of a town of 16 hectares area, consisting of 40% hard paved (k = 0.8), 30% unpaved (k = 0.20), and remaining as wooded (k =0.1), with a max. rain intensity of 5 cm/hr, would be computed by Rational formula, as equal to

Solution:

QUESTION: 9
