What is the maximum continuous operation time for the water mist system supply tank?

• A. 5 min
• B. 15 min
• C. 25 min
• D. 35 min

Answer: (B)

The amount of time the water mist system can run continuously is set by how much water is in the supply tank and how much water the system uses each minute. This is a simple t = V / Q relationship: if the tank holds V liters and the system draws Q liters per minute, the run time is V divided by Q. The tank for this design is sized to provide about fifteen minutes of operation at the system’s sustained misting flow. So the maximum continuous operation time is fifteen minutes. A shorter duration would mean a smaller tank or higher flow, while a longer duration would require a larger tank or lower flow, which isn’t how this system is configured.
