Air at 110 kPa and 45°C is flowing upward at a rate of 60 L/s through an inclined duct having a 6.2 cm diameter. The duct diameter is then reduced to 3.8 cm through a reducer (Figure 5). The pressure changes across the reducer and this change is measured by a manometer filled with water. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.15 m. Density of water is 1000 kg/m³. a) Find the pressure difference between the two inlets of the manometer. b) Determine the differential height (h) between the fluid levels of the two arms of the manometer. Data: Assume air as ideal gas. Ideal gas constant (R) = 0.287 kPa m³/kg K Note: Do not neglect the effect of air column height on the pressure change. Air Figure 5.
