Answer 2

Answer:

There is not enough information here.

If the pipes are not running at full capacity, then it could be the same or only slightly more. For example, if you are only running at a trickle on 6 pipes, you can probably go down to 3 or even 2 pipes and still have the same fill time.

If the pipes are running just barely at “full” capacity, then it will be pretty close to 6/5 the time or 96 minutes.

However, it doesn’t usually work exactly like that.

If the pressure on the source side is fixed, then what will happen is you’ll likely get more throughput through the remaining 5 pipes, but it won’t equate to the same amount of water moving through them. The exact number here depends on the exact situation, the size of the pipes, number of bends, and overall resistance.

In some situations, increasing the pressure can actually lead to LESS throughput per pipe as there was before, but that’s unlikely.

So the correct answer is “most likely somewhere between 80 and 96 minutes”.
