(8%) Problem 12: A Venturi meter is a horizontal tube with a wide section and a narrow section, each of which is attached to a vertical tube. The pressure difference between the vertical tubes, caused by fluid moving through the horizontal tube, is measured with a U-tube manometer. For the device shown, assume the ratio between the diameters is 4.01. Additionally assume that the fluid in the U-tube manometer is mercury with a density of 13, 600 kg/m'. Suppose that the fluid moving through the horizontal section is oil with a density of 783 kg/m', and the difference between the mercury levels on the left-hand and right-hand sides of the manometer is 3.16 cm. (Note that a pocket of air fills the portion of the narrow tube between the mercury and the horizontal tube, and this prevents the oil from entering the "U" portion of the U tube.) 33% Part (a) What is the ratio. R, of the speed of the fluid in the narrow section to the speed in the wide section? Grade Summ DeductionsPart (b) What is the magnitude of the pressure difference, in pascals, between the two vertical tubes? Part (c) What is the speed, in meters per second, of the fluid as it moves through the wide section of the horizontal tube? All coqun 0 8023 Hyper TA, LLC
