Question

Problem II: (25 points total) A horizontal pipe has a varying cross-section, as shown. Water is flowing in the pipe at a rate of 6.55 × 10?³ m³/s. The wider portions of the pipe have a cross-sectional area of 40.5 cm², while the constriction has a cross-sectional area of 12.3 cm². You may use ?water = 1000 kg/m³ ?mercury = 13.6 × 10³ kg/m³ Part A (5 points): Find the flow speeds at the wide and the narrow portions. Part B (10 points): Find the pressure difference between these portions. Part C (10 points): Find the difference in height between the mercury columns in the U-shaped tube. .

Step 1

Given: - Cross-sectional area at the wider portion (A1) = 40.5 cm² = 40.5 × 10^(-4) m² - Cross-sectional area at the constriction (A2) = 12.3 cm² = 12.3 × 10^(-4) m² - Flow rate = 6.55 × 10^(-3) m³/s Using the equation of continuity: A1V1 = A2V2 40.5 × 10^(-4) Show more…

Problem II: (25 points total) A horizontal pipe has a varying cross-section, as shown. Water is flowing in the pipe at a rate of 6.55 × 10⁻³ m³/s. The wider portions of the pipe have a cross-sectional area of 40.5 cm², while the constriction has a cross-sectional area of 12.3 cm². You may use ρwater = 1000 kg/m³ ρmercury = 13.6 × 10³ kg/m³ Part A (5 points): Find the flow speeds at the wide and the narrow portions. Part B (10 points): Find the pressure difference between these portions. Part C (10 points): Find the difference in height between the mercury columns in the U-shaped tube.
