Question

what is the second most common control variable in water systems? pressure temperature composition flow 14 multiple choice 1 point how might heavy rain result in the loss of fire water? it would actually increase available feed water. it would have no effect on available feed water. low - lying raw water pumps might be submerged. it would only affect potable water supplies. 15 multiple choice 1 point which of the following is not an impact of a chlorine leak? corrosion release of poison gas insufficient biological control

Explanation:

1. For water systems, flow is the most common control variable, making pressure the second most common.
2. Heavy rain can submerge low-lying raw water pumps, disrupting the supply of fire water and leading to loss.
3. Chlorine leaks release toxic gas, and reduced chlorine levels cause insufficient biological control; corrosion is not a direct impact of a chlorine leak.

Answer:

1. Pressure
2. Low-lying raw water pumps might be submerged.
3. Corrosion
