A level (horizontal) pipe contains a non-viscous, incompressible fluid with a density 1200 kg/m3 that is flowing steadily. At one position within the pipe, the pressure is 300 x 103 N/m2 and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 x 103 N/m2. What is the speed of the flow at this second position?

A horizontal pipe carries a smoothly flowing liquid of density of 1290 kg/m³. At Locations 1 and 2 along the pipe, the diameters are dj = 6.79 cm and d2 = 2.79 cm, respectively. Is the flow speed at Location 2 higher or lower than the flow speed at Location 1? d Location 1 Location 2 d2 O higher cannot tell from the data lower The flow speed at Location 1 is 1.87 m/s. What is the pressure difference AP between Location 2 and Location 1 (including its sign)? Ignore viscosity. AP = Ра

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 pw = 1.00 x 10° kg/m², fills the lower portion of the container to a depth of 0.206 m. The fluid that is floating on top of the water is 0.314 m deep. If the absolute pressure on the bottom of the container is 1.049 × 10° Pa, what is the density, p1, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po = 1.013 × 10° Pa. Pi = kg/m³

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 cylindrical disk of wood weighing 50.0 N and having a diameter of 25.0 cm floats on a liquid of density p= 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?

A drug is being delivered into the patient’s arm at the rate of 10mL per min. The drug is being delivered from s syringe through a 5 cm long needle with an internal diameter of 1 mm. If the patient blood is 100 mmHg. What must the pressure in the syringe be? ( drug viscosity = 8.9 x10-4 Pa s)

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 ?w=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 0.307 m deep. If the absolute pressure on the bottom of the container is 1.049×105 Pa, what is the density, ?l, of the unknown fluid? The acceleration due to gravity is ?=9.81 m/s2 and atmospheric pressure is ?0=1.013×105 Pa.

A submersible vehicle is in a lake at a depth of 29.6 m. What is the absolute pressure (in Pa) at this depth?
