Answer:
Flow rate of air is given as 83.33 cubic feet per minute
Explanation:
As we know that total volume of the air flow is given as
also we know that total time is
now we have flow rate given as
The equivalent resistance of resistors connected in parallel is
In our problem, we have 5 identical resistor of resistance
, so their equivalent resistance is
The problem also says that the equivalent resistance is
, so we can find the resistance R of each piece of wire:
In the initial wire, it's like the 5 pieces are connected in series, so the equivalent resistance of the wire is just the sum of the resistances of the 5 pieces:
