SUMMARY

To fill a child's inflatable wading pool with a diameter of 1.6 m to a depth of 25 cm using a garden hose with a diameter of 3 cm and a water speed of 1 m/s, Bernoulli's equation is not necessary for this calculation. The volume of the pool is approximately 80 liters, and with the hose's flow rate, it will take approximately 8,000 seconds to fill the pool. The flow rate from the hose can be calculated as 0.07 liters per second at 1 m/s.

Do I use Bernoulli's equation for this problem? If so, how do I go about plugging in the values?

To fill a child's inflatable wading pool, you use a garden hose with a diameter of 3 cm. Water flows from this hose with a speed of 1 m/s. How long will it take to fill the pool to a depth of 25 cm if it is circular and has a diameter of 1.6 m?

Sounds like a straight algebra word problem to me. Am I missing something? If the water is flowing through a 3cm diameter tube at 100cm/s, how many cc's of water per second come out the end? How many cc's of water to fill the pool volume in the problem?
 
Never mind, I figured this out. Thank you!
