  2. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    The turbine flowmeter (better described as an axial turbine) translates the mechanical action of the turbine rotating in the liquid flow around an axis into a user-readable rate of flow (gpm, lpm, etc.). The turbine tends to have all the flow traveling around it. The turbine wheel is set in the path of a fluid stream.

    However, manufacturers now offer ultra-efficiency showerheads with maximum flow rate below 2.0 gpm (7.6 lpm). Examples include a showerhead with flow rate of 1.75 gpm (6.61 lpm) at high water pressure and 1.45 gpm (5.48 lpm) at low pressure, or a showerhead with three pressure compensated flow rates (by non-removable pressure compensator) with ...

    en.wikipedia.org/wiki/K-factor_(fire_protection)

    K-Factors have also previously been calculated and published using the United States customary units of pound per square inch (psi) and gallon per minute (gpm). Within the United States, US measurements are still often used instead of metric. [3] [4]

  7. Gasoline pump - Wikipedia

    en.wikipedia.org/wiki/Gasoline_pump

    Light passenger vehicles pump up to about 50 litres (13 US gallons) per minute [8] (the United States limits this to 10 US gallons [38 litres] per minute [9]); pumps serving trucks and other large vehicles have a higher flow rate, up to 130 litres (34 US gallons) per minute in the UK [8] and 40 US gallons (150 litres) in the US. This flow rate ...

  8. Shower - Wikipedia

    en.wikipedia.org/wiki/Shower

    Low-flow shower heads that have a water flow of equal or less than 7.6 litres (1.7 imp gal; 2.0 US gal) per minute (2.0 gallons per minute), can use water more efficiently by aerating the water stream, altering nozzles through advanced flow principles or by high-speed oscillation of the spray stream.

  9. Fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Fluid_dynamics

    In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).
