    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 ...

    Q = flow, gpm (gallons per minute) C = pipe roughness coefficient; d = inside pipe diameter, in (inches) Note: Caution with U S Customary Units is advised. The equation for head loss in pipes, also referred to as slope, S, expressed in "feet per foot of length" vs. in 'psi per foot of length' as described above, with the inside pipe diameter, d ...

  5. 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.

    The relationship between gallons per minute (gpm) and fixture unit is not constant, but varies with the number of fixture units. For example, 1000 FU is equivalent to 220 US gallons per minute (0.014 m 3 /s) while 2000 FU represents only 330 US gallons per minute (0.021 m 3 /s), about 1.5 times the flow rate.

    Print speeds of 600 lines per minute [2] (approximately 10 pages per minute) were achieved in the 1950s, later increasing to as much as 1200 lpm. Line printers print a complete line at a time and have speeds in the range of 150 to 2500 lines per minute.

  9. Actual cubic feet per minute - Wikipedia

    en.wikipedia.org/wiki/Actual_cubic_feet_per_minute

    Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.
