- 1. Fluid Flow: Water runs into a fountain, filling all pipes, at a steady rate of 0.750 cubic meters per second. How fast will it shoot out of a hole 4.50 cm in diameter?If it takes 2.15 min to fill a 23.0 L bucket with water flowing from a garden hose of diameter 3.10 cm, determine the speed at which water is traveling through the hose. If a nozzle with a diameter two-fifths the diameter of the hose is attached to the hose, determine the speed of the water leaving the nozzle.2. Water flows through a fire hose of diameter 6.35 cm at a rate of 0.012 m³/s. The fire hose ends in a nozzle of inner diameter 2.20 cm. What is the speed with which the water exits the nozzle?
