How Fast Does Water Exit the Sprinkler Holes According to Bernoulli's Equation?

[aliz_khanz]

Homework Statement

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 ?

Homework Equations

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? $$\rho$$ = 999.7026 kg/m³ at T = +10 C
