Online calculator says 5280 feet x 26 diameter x 5 = Cubic Feet = 14,016,529.78 ft³.
AI is useful for something. To understand the volume of 1 million cubic feet, consider the following points:
This volume is roughly equal to the space of 10 average-sized homes.
It can hold about 1,000 standard shipping containers.
In terms of a swimming pool, it would fill about 40 Olympic-sized pools.
14 million would be 14 homes and about 56 Olympic-sized pools or 17,000 large home swimming pools.
The speed the water was flowing would be needed to calculate the second question.
Ah, your calculator used a more precise value of pi.
If we knew the typical cfm or cms that fed the power plant, we could easily calculate the additional water that entered the system before it was shut down.
