2. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   Most of the pumps are fitted with a 2.0 - 3.7 kW motor that receives energy from a 4.8 kW p PV array. The 3.7 kW systems can deliver about 124,000 liters of water/day from a total of 50 meters setoff head and 70 meters dynamic head. By 30 August 2016, a total of 120,000 solar PV water pumping systems had been installed around the world. [4]

3. Electric vehicle conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle_conversion

   Electric car conversion has gone from being exclusively conducted by hobbyists and enthusiasts, to a rapidly growing industry. [1] [2] U.S. Electricar was one of the first commercial electric car conversion companies, founded in the 1970s to sell converted versions of conventional cars in the United States using lead-acid battery storage systems.

4. Inverter compressor - Wikipedia

   en.wikipedia.org/wiki/Inverter_compressor

   In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.

5. Variable-frequency drive - Wikipedia

   Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

6. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   where Δp is the change in total pressure between the inlet and outlet (in Pa), and Q, the volume flow-rate of the fluid is given in m 3 /s. The total pressure may have gravitational, static pressure and kinetic energy components; i.e. energy is distributed between change in the fluid's gravitational potential energy (going up or down hill ...

7. Specific pump power - Wikipedia

   en.wikipedia.org/wiki/Specific_pump_power

   Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.
