    : FLUID MECHANICS: BERNOULLI EQUATION AND MOMENTUM EQUATION

    FLUID MECHANICS: BERNOULLI EQUATION AND MOMENTUM EQUATION Bernoulli Equation The Bernoulli equation comes from Newton’s law of motion. Assumptions used in deriving Bernoulli’s equation: Flow is steady Incompressible flow Non-viscous flow (ideal fluid with zero viscosity) No losses and no energy exchanges Bernoulli’s equation states that “Total head of a flowing fluid is constant or […]

    * Compressible flow (Gas Dynamics), Methods of Study and the Assumptions Used

    Compressible flow (Gas Dynamics) Compressible flow (gas dynamics) is that branch of fluid mechanics which deals with flow of fluids having significant changes in fluid density. Gases display such a behavior since liquids are incompressible.  Mach number  (the ratio of the speed of the fluid flow to the speed of sound) decides about the compressible […]

    * Normal Shock, Fanno line and Rayleigh Line in a Compressible Flow

    Normal Shock, Fanno line and Rayleigh Line in a Compressible Flow NORMAL SHOCK IN A COMPRESSIBLE FLUID FLOW When the flow passes from a supersonic to subsonic in a SMALL distance, the velocity decreases suddenly and pressure rises sharply. This sudden pressure rise is a normal to the pipe surface and is called the NORMAL […]
