fluid mechanics important question with answers
conservation of mass in fluid flow, stating that the mass flow rate remains constant in a steady, incompressible flow. Mathematically: \[ A_1 v_1 = A_2 v_2 \] Where: \( A_1, A_2 \) = cross-sectional areas at points 1 and 2 \( v_1, v_2 \) = velocities at points 1
