Calculation of centrifugal pump inlet pressure
Thread Content
Dear friends, is this how the inlet pressure of a centrifugal pump is calculated? I always feel that this algorithm is wrong, because part of the static pressure energy at the inlet is converted into kinetic energy. The inlet pressure should be the static pressure energy minus the pipeline resistance minus the kinetic energy\ud83d\ude00\ud83d\ude00 I hope you can give me active guidance.
0.1mpa lift height 10 meters seems like
There is a trend table that can be measured
Let’s look at the principles of chemical engineering and calculate based on Bernoulli’s equation.
The cavitation margin of this height pump is no problem
Subtract the kinetic energy! Why don't you list Bernoulli's equation? Just list it and you will know! .
I calculated the kinetic energy of the next 80 square meter pipe with a diameter of 150mm and the kinetic pressure head is only 0.07m. I feel something is wrong.
Did you not consider gauge pressure and absolute pressure?
