Energy and Reliability Considerations For Adjustable Speed Driven Pumps
(Energy Systems Laboratory (http://esl.tamu.edu), 1999-05)
Centrifugal devices such as pumps, fans, and compressors follow a general set of speed affinity laws:
Q2= Q1*(N2/N1) [Equation 1]; H2=H1*(N2/N1)2 [Equation2]; P2=P1*(N2/N1)3 [Equation 3]
where Q= flow rate, N = speed, ...
Screening Pumping Systems for Energy Savings Opportunities
(Energy Systems Laboratory (http://esl.tamu.edu), 1999-05)
In most industrial settings, energy consumed by pumping systems is responsible for a major part of the overall electricity bill. In some cases, the energy is used quite efficiently; in others, it is not. Facility operators ...
