Benoulli's Equation Problem

  1. Nov 1, 2009 #1
    1. The problem statement, all variables and given/known data

    A garden hose having internal diameter of 1.75cm is connected to a lawn sprinkler that consists merely of an enclosure with 24 holes each , each 0.05cm in diameter. If the water in the hose has a speed of 2m/s, at what speed does it leave the sprinkler holes ?

    2. Relevant equations

    3. The attempt at a solution

    I think the 24 holes will be multiplied with 0.05 in order to get the total speed and then later dividing it by 24 to get a single hole speed . But we don't know the density? Stumped !

    Perhaps You have to look up at the density of water? [tex]\rho[/tex] = 999.7026 kg/m3 at T = +10 C
