A5/8-inch (inside) diameter garden hose is used to fill a round swimming pool 6.1 m in diameter. how long will it take to fill the pool to a depth of 1.4 m if water flows from the hose at a speed of 0.40 m/s?

To solve the problem it is necessary to apply the concepts related to Discharge. The flow rate is the amount of volume of a fluid that circulates in a given time

By definition it is represented as

Where,

v = Velocity

A = Area

However, as the name implies it can also be represented as

Where,

V = Volume

t = time

In our case we have the values of,

Therefore replacing all these data in the previous equation we have

It will take about 6 days to fill the pool.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
