- The Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (ρ = 7.00 ✕ 102 kg/m3) through a hose having an outlet radius of 1.19 cm. The difference in pressure is measured to be P1 − P2 = 1.30 kPa and the radius of the inlet tube to the meter is 2.38 cm. 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. The pressures at the left and right ends are represented by scale readings. The pressure at the left end is labeled P1, and P1 is greater than the pressure at the right end labeled P2. (a) Find the…A garden hose with an internal diameter of 3.5 cm is connected to a (stationary) lawn sprinkler that consists merely of a container with 27 holes, each 0.27 cm in diameter.

- Air flows through a heating duct with a square cross-section with 6-inch sides at a speed of 4.3 ft/s. Just before reaching an outlet in the floor of a room, the duct widens to assume a square cross-section with sides equal to 13 inches. Compute the speed of the air flowing into the room (in ft/s), assuming that we can treat the air as an incompressible fluid.Two capillary tubes with an internal diameter of 1.6 mm and 0.96 mm were inserted into a liquid of 0.79g.cm-3, the difference between the capillary rises in the tubes was 1.1 cm.
