For a perfect incompressible fluid flowing continuously, the total energy of a particle remains constant as it moves from one location to another; this principle is known as ___________________?
Show answer Hide answer
Answer: C. Bernoulli equation
Explanation
Bernoulli equation states that for an inviscid, incompressible steady flow, total mechanical energy along a streamline remains constant. The sum of pressure energy, kinetic energy, and potential energy per unit weight remains uniform at all points. Energy conservation principles govern this fundamental relationship for ideal fluid motion along streamlines. Daniel Bernoulli published his groundbreaking hydrodynamic principle relating pressure, velocity, and elevation in fluids. The equation assumes zero frictional head loss, constant fluid density, and steady flow conditions. Each term in the Bernoulli equation represents a specific head dimension measured in units of length.
Civil engineers apply Bernoulli's principle to design venturi meters, pipe contractions, and siphon spillways. Aerodynamic lift on aircraft wings and pressure distributions around bridge piers utilize these energy equations. Real-world frictional losses are incorporated into extended energy equations using empirical friction loss factors. Continuity Equation expresses the conservation of mass for fluid flow across changing cross-sectional areas. Pascal law states that pressure applied to an enclosed fluid is transmitted undiminished in all directions. Archimedean principle governs buoyant forces on immersed bodies rather than energy conservation along streamlines.
