  2. Orifice plate - Wikipedia

    en.wikipedia.org/wiki/Orifice_plate

    Orifice plate showing vena contracta. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice [1] but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.

  3. Bending of plates - Wikipedia

    en.wikipedia.org/wiki/Bending_of_plates

    Bending of plates, or plate bending, refers to the deflection of a plate perpendicular to the plane of the plate under the action of external forces and moments. The amount of deflection can be determined by solving the differential equations of an appropriate plate theory .

  4. Types of press tools - Wikipedia

    en.wikipedia.org/wiki/Types_of_press_tools

    Top Plate: It is used to hold top half of the press tool with press slide. It is also called Bolster Plate. Punch Back Plate : This plate prevents the hardened punches penetrating into top plate. It is also called Pressure Plate or Backup plate. Punch Holder: This plate is used to accommodate the punches of press tool.

  5. Rupture disc - Wikipedia

    en.wikipedia.org/wiki/Rupture_disc

    A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.

  6. Pressure vessel - Wikipedia

    en.wikipedia.org/wiki/Pressure_vessel

    The ASME definition of a pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. [2]The Australian and New Zealand standard "AS/NZS 1200:2000 Pressure equipment" defines a pressure vessel as a vessel subject to internal or external pressure, including connected components and accessories up to the connection to external ...

  7. Venturi effect - Wikipedia

    en.wikipedia.org/wiki/Venturi_effect

    This type of pressure measurement may be more convenient, for example, to measure fuel or combustion pressures in jet or rocket engines. The first large-scale Venturi meters to measure liquid flows were developed by Clemens Herschel who used them to measure small and large flows of water and wastewater beginning at the end of the 19th century ...

  8. Plate heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Plate_heat_exchanger

    The plate geometry is one of the most important factors in heat transfer and pressure drop in plate heat exchangers; however, such a feature is not accurately prescribed. In the corrugated plate heat exchangers, because of narrow paths between the plates, there is a large pressure capacity and the flow becomes turbulent along the path.

  9. Axial piston pump - Wikipedia

    en.wikipedia.org/wiki/Axial_piston_pump

    The operating pressure reaches, say, 200 bar (20 MPa or 2900 psi) and the swash plate is driven towards zero angle (piston stroke nearly zero) and with the inherent leaks in the system allows the pump to stabilize at the delivery volume that maintains the set pressure. As demand increases the swash plate is moved to a greater angle, piston ...
