The correct answer is B. 2.0.<\/p>\n
The ratio of the maximum daily sewage flow to the average daily sewage flow is called the peak factor. The peak factor is a function of the size of the sewer, the type of sewer, and the climate. For trunk sewers more than 1.25 m in diameter, the peak factor is typically assumed to be 2.0. This means that the maximum daily sewage flow is twice the average daily sewage flow.<\/p>\n
The peak factor is important because it affects the design of sewers. Sewers must be able to handle the maximum daily sewage flow without overflowing. The peak factor is also used to calculate the capacity of pumping stations and treatment plants.<\/p>\n
The peak factor is typically assumed to be 2.0 for trunk sewers more than 1.25 m in diameter. However, the peak factor can be higher or lower depending on the specific circumstances. For example, the peak factor may be higher in areas with a large population or in areas with a lot of industry. The peak factor may also be lower in areas with a lot of open space or in areas with a lot of trees.<\/p>\n
The peak factor is an important factor in the design of sewers. It is important to choose a peak factor that is appropriate for the specific circumstances.<\/p>\n","protected":false},"excerpt":{"rendered":"
