Water at a pressure of 3.85 x 105 N/m2 at street level flows into an office building at a speed of 0.68 m/s through a pipe with a radius of 2.5 cm. The pipe tapers down to 1.4 cm in diameter by the top floor, 18 m above the street. The flow speed is 2.2 m/s at the top floor. Calculate the pressure in the pipe on the top floor.

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.65 ✕ 105 Pa and the pipe radius is 2.60 cm. At the higher point located at y = 2.50 m, the pressure is 1.29 ✕ 105 Pa and the pipe radius is 1.40 cm. a) Find the speed of flow in the lower section. b) Find the speed of flow in the upper section. c) Find the volume flow rate through the pipe.

Water is carried through a pipe. At point A, the diameter is 20 cm and the pressure is 130 kPa. At point B, which is 4.0 m higher than point A, the diameter is 30 cm. If the flow is 0.08 m^3/s, what is the pressure at the second point? 9.3 kPa Not any of the choices listed 93 Pa 0.92 atm 930 mmH20

Water is supplied to an office building 30.0 m high through a pipe at ground level. (a) Find the minimum pressure in the supply pipe so that water can reach the top floor of the building. (b)Suppose the pressure in the supply pipe is designed so that water can flow out through a much smaller pipe on the top floor at a speed of 5.0 m/s. Find the pressure in the larger pipe on the ground floor.
