  2. Euler's pump and turbine equation - Wikipedia

    en.wikipedia.org/wiki/Euler's_pump_and_turbine...

    With the help of these equations the head developed by a pump and the head utilised by a turbine can be easily determined. As the name suggests these equations were formulated by Leonhard Euler in the eighteenth century. [1] These equations can be derived from the moment of momentum equation when applied for a pump or a turbine.

  3. Centrifugal pump - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump

    Centrifugal pumps with an internal suction stage such as water-jet pumps or side-channel pumps are also classified as self-priming pumps. [10] Self-Priming centrifugal pumps were invented in 1935. One of the first companies to market a self-priming centrifugal pump was American Marsh in 1938. [citation needed]

  4. Turbomachinery - Wikipedia

    en.wikipedia.org/wiki/Turbomachinery

    These two types of machines are governed by the same basic relationships including Newton's second Law of Motion and Euler's pump and turbine equation for compressible fluids. Centrifugal pumps are also turbomachines that transfer energy from a rotor to a fluid, usually a liquid, while turbines and compressors usually work with a gas. [1]

  5. Centrifugal pump selection and characteristics - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump_selection...

    Discharge Head, is the net head obtained at the outlet of a pump. For a centrifugal pump, the discharge pressure depends on the suction or inlet pressure as well, along with the fluid’s density. Thus, for the same flow rate of the fluid, we may have different values of discharge pressure depending on the inlet pressure.

  6. Euler equations (fluid dynamics) - Wikipedia

    en.wikipedia.org/wiki/Euler_equations_(fluid...

    In fluid dynamics, the Euler equations are a set of partial differential equations governing adiabatic and inviscid flow. They are named after Leonhard Euler . In particular, they correspond to the Navier–Stokes equations with zero viscosity and zero thermal conductivity .
