FE Civil Exam Prep 47, Continuity, Bernoulli, and Momentum

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The Continuity Equation (A1V1 = A2V2) applies to incompressible flow and shows how fluid velocity must increase as the cross-sectional area decreases. - Bernoulli's equation is a statement of energy conservation for an ideal fluid, balancing pressure head, velocity head, and elevation head, but it is only valid for steady, incompressible, and frictionless flow. - The Momentum Equation (F = ρQΔV) is used to calculate forces exerted by moving fluids, such as on pipe bends or vanes, and requires vector analysis. - A common exam trap is misapplying Bernoulli's equation where friction is present; in such cases, the full Energy Equation with a head loss term is necessary. - Remember that velocity and force in the Momentum Equation are vectors; always break the problem down into x and y components to solve for resultant forces correctly.
