Task id10767
Two horizontal pipes with diameters d1 = 0.075 m and d2 = 0.1 m are connected by flanges, between which there is a thin plate with a hole with a diameter d = 0.05 m, the center of which coincides with the axis of the pipe. A mercury U-shaped manometer is connected by means of water-filled tubes at a distance above and below the holes where the flow can be considered equalized. Manometer reading H = 349 mm Hg. at water flow Q = 0.014 m3/s. Assuming that pressure losses occur only when the jet expands below the hole, determine the compression ratio of the jet in the hole.
