The gauge pressure at the bottom of a cylinder of liquid is pg = 0.40 atm. The liquid is poured into another cylinder with twice the radius of the first cylinder. What is the gauge pressure at the bottom of the second cylinder?

An ideal fluid is flowing with a speed of 12 cm/s through a pipe of diameter 5 cm. The pipe splits into three smaller pipes, each with a diameter of 2 cm. What is the speed of the fluid in the smaller pipes?

Motor oil, with a viscosity of 0.25 N s/m , is flowing through a tube that has a radius of 3.0 mm and is 1.0 m long. The drop in pressure over the length of the tube is 200 kPa. What is the average speed of the oil?

(a) A submersible vehicle is in a lake at a depth of 26.0 m. What is the absolute pressure (in Pa) at this depth? The density of the water in the lake is 1.00 × 103 kg/m, and the air above is at a pressure of 101.3 kPa. Pa (b) The submersible vehicle has a circular window with a diameter of 38.0 cm. What force (in N) is exerted by the water on the window of the vehicle at the depth from part (a)? (Enter the magnitude.) Need Help? Read It

A pipe 10 meters in length is attached horizontally to a water pump. The pipe has an inner diameter of 3.0 cm and water is pouring out of the end that is open to the atmosphere at a rate of 2.0 L/s.

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 cylindrical disk of wood weighing 50.0 [N] and having a diameter of 25.0 [cm] floats on a liquid of density ? = 0.750 [g/cm3 ]. The cylinder of liquid is 60.0 [cm] high and has a diameter that is the same as that of the wood. What is the gauge pressure halfway down the liquid?

You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of ρw=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.215 m. The fluid that is floating on top of the water is 0.335 m deep. If the absolute pressure on the bottom of the container is 1.049×105 Pa, what is the density, ρl, of the unknown fluid? The acceleration due to gravity is g=9.81 m/s2 and atmospheric pressure is P0=1.013×105 Pa.

A barber’s chair with a person in it weighs 2150 N. The output plunger of a hydraulic system begins to lift the chair when the barber’s foot applies a force of 70 N to the input piston. Neglect any height difference between the plunger and the piston. What is the ratio of the radius of the plunger to the radius of the piston?

A force of 295 N is applied to a hydraulic jack piston that is 0.026 m in diameter. The second piston that supports the load has a diameter of 0.19 m. What is the magnitude of the output force on the hydraulic jack? Ignore any difference in height between the pistons. [Area of a circle = nr² or (T1/4)d²] %3D F1 F2 A1 A2
