1. what is an altitude valve used for?

a. to prevent storage tanks from filling too fast
b. to prevent storage tanks from overflowing
c. to separate the inlet and outlet flows
d. none of the above

1. how frequently should water storage reservoirs be completely inspect

a. every year
b. every other year
c. every 3 to 5 years
d. every 5 to 10 years

1. without storage, how much should pumping capacity be approximatel

a. twice the average requirement
b. three times the average requirement
c. less than the average requirement
d. none of the above

1. what percent can fire demand account for?

a. 10% of storage
b. 25% of storage

Explanation:

1. An altitude valve (level control valve) is designed to automatically stop inflow to a storage tank when it reaches a set water level, preventing overflow.
2. Standard guidelines for water storage reservoir full inspections recommend a 3 to 5 year interval to check for structural integrity, contamination, and component function.
3. Without storage to meet peak demand, pumping capacity must cover the maximum hourly demand, which is approximately twice the average daily demand.
4. Fire demand typically accounts for up to 25% of water storage requirements in water system planning to ensure sufficient supply for fire suppression.

Answer:

1. b. to prevent storage tanks from overflowing
2. c. every 3 to 5 years
3. a. twice the average requirement
4. b. 25% of storage
