The figure shows two sections of an old pipe system that runs through a hill, with distances dA = dB = 31.0 m and D = 105 m. On each side of the hill, the pipe radius is 2.30 cm. However, the radius of the pipe inside the hill is no longer known.To determine it, hydraulic engineers first establish that water flows through the left and right sections at 2.10 m/s. Then they release a dye in the water at point A and find that it takes 92.0 s to reach point B. What is the average radius of the pipe within the hill? Number A D Units dB B

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.85 x 105 Pa and the pipe radius is 2.70 cm. At the higher point located at y = 2.50 m, the pressure is 1.27 x 105 Pa and the pipe radius is 1.30 cm.

The lower section of a constricted pipe has a diameter of 8 cm. The upper section of the pipe, located 0.1 m above the lower section, has a diameter of 3 cm. The pressure at the lower section is 2.1 ×× 104 Pa, while the pressure in the upper section is 1 ×× 104 Pa. Assuming water moves through the pipe in a steady flow, calculate the speed (in m s-1) of the flow in the lower section. The density of water is 1000 kg m-3.

A firefighter mounts the nozzle of his fire hose a distance 32.1 m away from the edge of a burning building so that it sprays from ground level at a 45° angle above the horizontal. After quenching a hotspot at a height of 9.33 m, the firefighter adjusts the nozzle diameter so that the water hits the building at a height of 17.5 m. By what factor was the nozzle diameter changed? Assume that the flow rate of water through the hose stays the same, and treat the water as an ideal fluid. factor by which the hose diameter changed:
