Fire hoses used in major structure fires have inside diameters of 2.500 in (1 in = 2.54 cm). The nozzle of the fire hose have an inside diameter of 1.200 in. When firefighters are fighting a fire 2020.007 cm above the ground, the pressure in the nozzle is less than at ground level. When measured, the gauge pressure in the nozzle is 0.000 Pa.

(a) How are the firefighters able to fight a fire with zero water pressure? Explain your answer.

(b) What is the value of the water pressure as it emerges into the air from the nozzle? Explain your answer.
