Air at 105 kPa and 310 K flows upward through a 8-cm-diameter inclined duct at a rate of 65 L/s. The duct diameter is then reduced to 4 cm through a reducer. The pressure change across the reducer is measured by a water manometer.The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.20 m. Take the density of water to be p = 1000 kg/m³. The gas constant of air is R = 0.287 kPa-m³/kg-K. Determine the differential height between the fluid levels of the two arms of the manometer in centimeters.
