SUMMARY

The discussion centers on calculating the speed of water flowing through a hose with a diameter of 2 cm, used to fill a 20 L bucket in 1 minute. The relevant equations include Bernoulli's equation and the flow rate formula, which is defined as flow rate = A * v, where A is the cross-sectional area and v is the velocity. The user initially struggled with determining the pressures involved but later calculated a water speed of 1.06 m/s using the hose's cross-sectional area. This calculation is valid and demonstrates the application of fluid dynamics principles.

PREREQUISITES
  • Understanding of Bernoulli's equation

Homework Statement



A water hose 2 cm in diameter is used to fill a 20 L bucket. If it takes 1 min to fill the bucket, what is the speed at which the water moves through the hose ( note 1L= 1000cm^3)

Homework Equations


Bernoulli's equation
P1+.5pv^2+pgh1=P2+.5pv^2+pgh2

The Attempt at a Solution


I tried to plug various numbers in, however the problem is unspecific and i am stuck on how to find pressures 1 and 2. can someone explain this to me?

Have you tried the equation flow rate=Av?
 
Yeah after i posted this question i looked through the book and found that formula... but i used it for the area of the base of the hoseis rather than the bucket and got 1.06 m/s... is that okay?
