Regarding the calculation of filter pressure drop
Thread Content
Where does the formula for the cartridge filter inside come from? Could any expert give some advice?
It’s obtained through experiments. In engineering, a curve is drawn by connecting several points from experimental data, and then a formula is derived using multivariable functions. What is this method called? I’ve forgotten. Many formulas in engineering are derived in this way
Thank you. Although the formula was derived from experiments, was it cited from that book or paper?
The Y type is specified in version SH3411‑1999; I’m not sure about the cylinder shell, but HG/T20570.7 can be checked
I am very grateful for the reply from the expert above; there is no filter in HGT20570. I just want to know which book contains the formula for calculating pressure loss in cartridge filters, and I would like to understand the explanations and definitions of the parameters used in that formula.
It’s all copied from abroad; who knows where it comes from. It was copied from the Soviet Union before 1980, and later everything was completely copied from abroad
