PROBLEM 2 Consider a firefighter who is standing on a ladder and spraying water with a hose into Chief Inspector Jacques Clouseau's (Figure 3a) third-story apartment. A diagram of the hose/nozzle used by the firefighter is shown in Figure 3b. Assume the nozzle has little effect on the flow in the hose and water in the hose/nozzle is incompressible. The temperature of the water in the hose is 15°C. (a) Chief Inspector Jacques Clouseau investigating the cause of the fire in his apartment. water hose diameter=10cm outlet diameter=5cm Figure 3 个个个 outlet velocity=6ms-1 (b) Fire hose/nozzle used to extinguish the fire in Inspector Clouseau's apartment.
