2. Low-flow fixtures - Wikipedia

   en.wikipedia.org/wiki/Low-flow_fixtures

   Kitchen and bathroom faucets were limited to a flow rate of 2.2 gpm (gallons per minute) at 60 psi, and residential shower heads were limited to a flowrate of 2.5 gpm at 80 psi. [ 3 ] In response to an increasing number of water shortages and increased water utility rates there has been recent legislation by many states leading the way in water ...

3. 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 ...

7. Horsepower - Wikipedia

   en.wikipedia.org/wiki/Horsepower

   SAE tightened its horsepower rules to eliminate the opportunity for engine manufacturers to manipulate factors affecting performance such as how much oil was in the crankcase, engine control system calibration, and whether an engine was tested with high octane fuel. In some cases, such can add up to a change in horsepower ratings.
