A liquid (? = 1.65 g/cm3) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm2, the flow speed is 249 cm/s, and the pressure is 1.20  105 Pa. In the second section, the cross-sectional area is 4.00 cm2. (image) The flow within a horizontal tube is depicted by five lines. The tube extends from left to right, with the left end wider than the right end. The five lines start at the left end, go horizontally to the right, curve slightly toward the center of the tube such that all five lines come closer together, and again go horizontally to the right to exit at the right end. Arrows on the lines point to the right to represent the direction of flow.    (a) Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.)   m/s The answer is 6.225 m/s.  (b) Calculate the smaller section's pressure.

Oil with a density of 890 kg/m³ moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P, = 1.95 × 104 Pa, and the pipe diameter is 8.00 cm. At another point y = 0.20 m higher, the pressure is P, = 1.15 × 104 Pa and the pipe diameter is 4.00 cm. (a) Find the speed of flow (in m/s) in the lower section. m/s (b) Find the speed of flow (in m/s) in the upper section. m/s (c) Find the volume flow rate (in m³/s) through the pipe. m3/s

In the hydraulic system shown in the figure (see below) the piston on the left has a diameter of 5.2 cm and a mass of 2.0kg. The piston on the right has a diameter of 15 cm and a mass of 3.6 kg. If the density of the fluid is 700 kg/m^3, what is the height difference h between the two pistons?

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?

The figure below shows a horizontal pipe with a varying cross section. A liquid with a density of 1.65 g/cm³ flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm², and while in this side, the speed of the liquid is 2.72 m/s, and the pressure is 1.20 × 105 Pa. The right side's cross sectional-area is 4.00 cm². (a) What is the speed (in m/s) of the liquid in the right side (the smaller section)? (Enter your answer to at least three significant figures.) m/s (b) What is the pressure (in Pa) of the liquid in the right side (the smaller section)? Pa

The U-tube in the figure contains two liquids in static equilibrium: Water of density ???? = 998 ????/??3 is in the right arm, and oil of unknown density ???? is in the left. Measurement gives ℓ = 135 mm and ?? = 12.3 mm. What is the density of oil.
