- Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.70 x 105 Pa and the pipe radius is 2.90 cm. At the higher point located at y = 2.50 m, the pressure is 1.27 x 105 Pa and the pipe radius is 1.70 cm. (a) Find the speed of flow in the lower section. m/s (b) Find the speed of flow in the upper section. m/s (c) Find the volume flow rate through the pipe. m³/sA dart gun contains a spring of spring constant k = 16 N/m which is used to shoot a dart of mass m. The dart leaves the gun at a speed of v = 3.1 m/s after the spring is compressed 1 cm. what is the darts speed when it hits the floor (vf in m/s) if it is fired horizontally at a height of h = 2 m what angle in degree does the darts final velocity make with the horizontal?(a) What is the pressure drop (in N/m2) due to the Bernoulli effect as water goes into a 2.50 cm diameter nozzle from a 8.70 cm diameter fire hose while carrying a flow of 38.0 L/s? N/m2 (b) To what maximum height (in m) above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.) m
