A water supply maintains a constant rate of flow for water in a hose. you want to change the opening of the nozzle so that water leaving the nozzle reaches a height that is four times the current maximum height the water reaches with the nozzle vertical. to do so, what should you do?

The answer for the problem is explained through this: From V = √(2 g y), the velocity would need to double if the height quadruples. So if we need to double the velocity, the area must be reduce by a factor of 2, assuming producing the same flow rate.
