Extracted text: Water with density Pwater = 1000 kg/m³ flows through a pipe, composed of two reduced in size sections, as shown on the figure. The two sections are Ilinked with a flange connection, and the corresponding diameters are D, = 8 cm and D, = 5 cm. If the velocity in cross-section 1 is v, = 5 m/s, and the readings of the connected liquid manometer is h = 60 cm, determine the reaction force acting over the flange connection. The manometric fluid is mercury, with density Pa-101kPa %3D Mercury Pmercury = 13600 kg/m³.
