A fireman climbs a 10 m high ladder carrying
a 5 in diameter hose that has a 1.5 in diameter
nozzle. The pump has an absolute pressure of
3 atm .
What is the water velocity from the nozzle?
Assume that water is incompressible, its density is 1000 kg/m3
, and 1 inch = 0.0254 m.
The acceleration of gravity is 9.8 m/s
2
and 1
atm = 1.01 × 105 Pa.
