Fluids Problem

  1. Jan 9, 2010 #1
    1. The problem statement, all variables and given/known data

    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)

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

    3. 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?
