(chatquestion)...Air at 105 kPa and 37°C flows upward steadily through a 6-cm diameter inclined duct at a rate of 65 L/s. The duct diameter is then reduced to 4 cm through a reducer as shown in Figure 3. 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 are attached is 0.20 m. Determine the change of elevation height, h of the fluid levels in the two arms of the manometer. Molar mass for air is 0.02897kg/mol. (Guide: Find the density of air using ideal gas law. Use Bernoulli equations at two points with the points located at each of the manometer arms to determine the pressure drop across the two points. Then, determine the height from hydrostatic pressure formula) Air h Figure 3
