SUMMARY
The discussion focuses on calculating the speed at which water exits the holes of a lawn sprinkler using Bernoulli's Equation. Given a garden hose with an internal diameter of 1.75 cm and a water speed of 2 m/s, the sprinkler has 24 holes, each with a diameter of 0.05 cm. The correct approach involves applying the principle of conservation of mass, specifically the equation of continuity, to determine the exit speed of water from the holes, which is approximately 9.6 m/s. The density of water at 10°C is noted as 999.7026 kg/m³, which is relevant for further calculations.
