A circular duct carrying water gradually contracts from a diameter of 30 cm to 15 cm. The figure (not drawn to scale) shows the arrangement ofdifferential manometer attached to the duct. When the water flows, the differential manometer shows a deflection of 8 cm of mercury (Hg). Thevalue of the specific gravity of mercury and water are 13.6 and 1.0, respectively. Consider the acceleration due to gravity. g = 9.81 m/s². Assumingfrictionless flow, the flow rate (in m³/s, rounded off to 3 decimal places) through the duct isT30cm18cmMercury0 4 14 502515cm
