evidence: P.1. Water is flowing in a fire hose with a velocity of 1.5 m/s and a pressure of 250,000 Pa. At the nozzle the pressure decreases to atmospheric pressure (101,300 Pa), there is no change in height. Use the Bernoulli’s equation to calculate the velocity of the water exiting the nozzle. (The density of water is 1000 kg/m3 and gravity g is 9.8 m/s2)
