A student wants to design a water fountain that sprays water to a maximum height. If the fountain has a nozzle with a diameter of 3 cm and water flows through it at a rate of 2 liters per second, what is the maximum height the water can reach? (Assume that the fountain is operating at sea level under standard atmospheric conditions and neglect any frictional losses.)
