If the per capita contribution of suspended solids and BOD is 90 gm and 55 gm, find the population equivalents of

1. A combined system serving 1000 persons and having 75 gm per capita daily of BOD.

2. 40,000 litres daily of industrial wastewater containing 1800 mg/l of suspended solids. Respectively,

Consider the following statements.

1. Hydraulic gradient required to initiate " quick" condition is independent of the ratio of volume of voids to volume of solids in a soil mass. 

2. Initiation of piping under hydraulic structures can be prevented by increasing the length of flow path of water.

3. Seepage pressure is independent of the coefficient permeability.

In a certain irrigation project and in a given year, 72% and 56% of the culturable command area remained unirrigated in Kharif and Rabi season, then the intensity of irrigation for that year and for that project, will be

Consider the following statements:

In the water supply distribution network,

1) The gridiron system requires more lengths of pipelines and a larger number of cut-off valves.

2)  Employing a gridiron system, Repair works can be easily done without affecting the other users.

3) In a dead-end system, the pressure is almost constant and very high at remote parts.

4) Dead end system requires less number of cut-off valves and more number of & scour valves.

Which of these statements are correct?
