A 1.00 m tall pipe is filled to the halfway level with glycerin and then to the top with water. What is the gauge pressure at the bottom?

water flows through a section of pipe at a speed of 9.72 m/s. the water that flows into a 6.47 m higher section of pipe or flows at a speed of 1.45 m/s. what is the difference in the pressure between the two section of pipes? Report 3 significant digits.

A horizontal pipe decreases uniformly from 150 mm diameter to 100 mm diameter in the direction of the flow of water. The pressure at the narrow section of the pipe is 2.2×105 N/m2, when the flow rate is 0.12 m3/s . Assuming there are no friction losses, calculate the pressure at the 150 mm side.

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.85 ✕ 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 ✕ 105 Pa and the pipe radius is 1.30 cm. A pipe is open at both its left and right ends. The pipe starts at the left end, extends horizontally to the right, curves up and to the right, and extends horizontally to the right again. The right end is higher than its left end, and the change in height is labeled y. The diameter at the right end is smaller than the diameter at the left end. The pressure at the left end is labeled P1, and the pressure at the right end is labeled P2. (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/s
