Seeking advice on the characteristic curve of centrifugal pumps
Thread Content
In the performance curve of a centrifugal pump, should the flow rate be expressed in m3 per second or cubic meters per hour when performing calculations? What are the other units? Thank you
The flow rate is usually expressed in cubic meters per hour, m3/h
Performance curves generally include the following: flow rate in m3/h, head in M, power in KW, and efficiency in %
Flow rate m3/h, Head m, Power KW, Efficiency %
Perhaps I didn’t explain it clearly; I’m sorry, experts. These past couple of days I read a book titled \"Pumps for Chemical Processing,\" in which the flow rate unit used to calculate the pipeline characteristic curves was cubic meters per hour. However, in the book \"Pumps and Fans,\" the flow rate unit in the formulas for calculating pump pipeline characteristic curves was cubic meters per second. I’m not sure why there’s this difference Thank you
