There's a term used for people who circumvent security to do things on someone else's computerunemployed.
Assuming all three hoses have the same back pressures (nozzles): The flow of water should divide equally among the three hoses, the speed being INVERSELY proportional to their cross-sectional areas: (0.019)?/(0.076)? 0.0625 {ratio of hose area to hydrant pipe area} speed of water in each hose 2.5/0.0625 40 m/s ANS b. area of 1 fire hose πR? π(0.019)? 1.134E-3 m? volume flow of water thru 1 fire hose 40(1.134E-3) 0.04536 m?/s total volume flow of water {3 hoses} 3(0.04536) 0.1361 m?/s total mass flow of water by all three hoses in one second 0.1361E3 ≈ 136 kg/s total mass of water on fire in 1 hr 136(3600) 490,000 kg ANS (a)
