Answer:
Approximately 4.58 minutes.
Step-by-step explanation:
The diameter of hose is in centimeters, that is 2.9 cm.
Velocity is in m/s that can be converted into cm/s.
Let the velocity be 'v'.
v = 3.3 m/s= 330 cm/s
The amount of water following through the cross sectional area of the hose is.
diameter = 2.9 cm
The cross sectional are of the hose is approximately . To volume of water that flows through the hose each second, multiply its velocity by the cross sectional area of the hose.
Volume/ second =
This is approximately . There are in one liter.
Total volume
To determine the time in seconds, divide the total volume by the volume per second.
t =
This is roughly 275 seconds.
We can convert 275 seconds into minutes.
t (mins) = minutes.
So it will take 4.58 minutes to fill the wading pool.
