  2. Flow coefficient - Wikipedia

    en.wikipedia.org/wiki/Flow_coefficient

    A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s , e.g. water.

  3. Heat capacity ratio - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity_ratio

    In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).

  4. Steam turbine governing - Wikipedia

    en.wikipedia.org/wiki/Steam_turbine_governing

    In this method groups of two, three or more nozzles form a set and each set is controlled by a separate valve. The actuation of individual valve closes the corresponding set of nozzle thereby controlling the flow rate. In actual turbine, nozzle governing is applied only to the first stage whereas the subsequent stages remain unaffected. [1]

  6. Hydraulic clearance - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_clearance

    Leakage in narrow clearance, spool valve. Hydraulic clearance. Flow in narrow clearances are of vital importance in hydraulic system component design. The flow in a narrow circular clearance of a spool valve can be calculated according to the formula below if the height is negligible compared to the width of the clearance, such as most of the clearances in hydraulic pumps, hydraulic motors ...

    en.wikipedia.org/wiki/Hazen–Williams_equation

    The Hazen–Williams equation is an empirical relationship that relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction.
