What are the conditions under which the flow rate and head values on the pump and fan samples apply? ?
First of all, thank you very much for your generous answer. I also want to ask: under what pressure and temperature conditions is it? ? Thank you!
Regarding some of the questions you asked upstairs, the books provide basic explanations that are quite clear. Instead of asking here, it’s better to go and read the books first; otherwise you will face many more basic questions. Anyone who has studied the section on pumps in chemical engineering principles knows that the experimental conditions under which head is determined are clearly stated there
A sample manual should contain its testing conditions
The flow rate and head at the point of maximum efficiency are called the rated flow rate and rated head
The flow rate and head of the pump refer to the values under standard atmospheric pressure, with clean water as the medium and a temperature of around 20 degrees Celsius
