A fire starts in an apartment building in downtown Boston. When the firefighters arrive, they immediately get to work putting out the fire using a fire hose. The water for the fire hose is provided by a fire hydrant at ground level. Assume that the velocity of the liquid coming from the fire hydrant is 1.6 m/s, and that the pressure at the hose nozzle is atmospheric pressure (101000 Pa). a. The firefighters start with the ground floor, so there is no change in height between the fire hydrant and the hose nozzle. If the velocity of the water coming out of the nozzle is 12.8 m/s, find the pressure at the fire hydrant in units of Pa. b. After the ground floor fire is put out, another fire is spotted on another floor. A firefighter carrying the hose is lifted on a platform to the same height as the fire, which is 44.35 m above the ground. Assuming that the pressure found in part a) remains constant, what would be the new velocity of the water coming out of the nozzle at this new height?

. Indiana Jones needs to ascend a high-rise building. There is a large hose filled with pressurized water hanging down from the building top. He builds a square platform and mounts four 4-cm-diamter nozzles pointing down at each corner. By connecting hose branches, a water jet can be produced from each nozzle. Jones, the platform, and the nozzles have a combined mass of 150 kg. Determine the minimum water jet velocity needed to raise the system.
Water is flowing in a fire hose with a velocity of 1 m/s and pressure of 2.8 bar. At the nozzle the pressure decreases to atmospheric pressure 1 bar, there is no change in height. Calculate the velocity of the water exiting the nozzle. (Hint: The density of water is 1000 kg/m³ and gravity g is 9.8 m/s²). the velocity at the nozzle in m/s
