Fluid Mechanics Sample Problems
ntinuity equation to find velocity in the narrow section: 1. \[ A_1 V_1 = A_2 V_2 \] where \( A = \pi d^2 / 4 \). Apply Bernoulli’s equation to find pressure difference. 2. **Calculations:** \( A_1 = \pi (0.3)^2 /4 = 0.0707 \, m^2 \) \( A_2 = \pi (0.15)^2 /4 = 0.0177 \,
