how to define pressure drop formula in a pipe
Hello,
i have obtained a mathematical formula of pressure drop as a function of mass flow rate, with experimental data. I'd like to know how to impose a pressure drop in a pipe, given for the mathematical formula. I think a UDF is needed, for reading the mass flow rate and obtain the pressure drop with the formula. Some orientation or informatino about this would be helpfull. Thanks ins advance. Best regards.

Just set the pressure drop you require via two pressure BCS.

Hi, I am a graduate student from OSU and i would like to know the equation u derived for pressure drop as a function of mass flow rate. Is the equation derived by using Darcy's Weisbach equation? I am having some kind of same problem that deals between the two of these parameters. Please do send me a reply
