What are the pump laws?
What are the pump laws? The affinity laws (Also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. Do affinity laws apply to compressors? Changes in compressor performance can be determined whenever the speed fluctuates by simply utilizing the affinity laws. In essence, the flow coefficient represents the “normalized flow rate” of the compressor at any speed. Are affinity laws accurate? Note...
