Final answer:
The maximum height to which water can be squirted with the hose in Example 12.2 if it emerges from the nozzle is 4.38 m.
Step-by-step explanation:
The maximum height to which water can be squirted with the hose can be calculated using Bernoulli's equation.
The height is determined by the pressure drop due to the Bernoulli effect as the water goes into the nozzle.
The maximum height can be found by using the equation h = (P₂ - P₁) / (p * g), where P₂ is the pressure inside the nozzle, P₁ is the atmospheric pressure, p is the density of water, and g is the acceleration due to gravity.
In this example (Example 12.2), the maximum height is 4.38 m (option a).
