A nozzle with a radius of 0.16 cm is attached to a garden hose with a radius of 0.88 cm that is pointed straight up. The flow rate through hose and nozzle is 0.35 L/s.
Part (a) Calculate the maximum height to which water could be squirted with the hose if it emerges from the nozzle in m.

Part (b) Calculate the maximum height (in cm) to which water could be squirted with the hose if it emerges with the nozzle removed, assuming the same flow rate.

Expert Solution

This problem can be solved by applying Bernoulli's equation. But before that, intuitively speaking, we can say that the maximum height in the first case where the water emerges from the nozzle, would be greater than the maximum height in the second case. This is because, the flow rate is the same but the area of the nozzle is smaller, implying that the velocity of the water would be more in this case, thus pumping it higher. With this in mind, please follow the following solution:

2. A garden hose attached to a nozzle is used to fill a 15-gal bucket. The inner diameter of the hose is 1.5 cm, and it reduces to 0.8 cm at the nozzle exit. If it takes 50 s to fill the bucket with water (density = 1 kg/L), determine (a) the volume and mass flow rates of water through the hose, and (b) the average velocity of water at the nozzle exit.

A fire hose has an inside diameter of 6.40 cm. Suppose such a hose carries a flow of 40.0 L/s starting at a gauge pressure of 1.62×106N/m2 . The hose goes 10.0 m up a ladder to a nozzle having an inside diameter of 3.00 cm. Calculate the Reynolds numbers for flow in the fire hose and nozzle to show that the flow in each must be turbulent.
