What unit is mm/m?
Thread Content
When calculating pipeline pressure loss, the unit is mm/m – what does that mean? What’s the meaning?
This is probably the expansion coefficient of the pipe material, and it also depends on temperature
Energy loss can be expressed in meters; pipeline loss refers to the energy value corresponding to a certain number of millimeters of loss per meter of pipeline. Refer specifically to Bernoulli’s equation.
It’s understandable, but it’s not as intuitive as PA; I still don’t quite get it
It’s probably the amount of pressure in millimeters of water column lost per meter of pipeline!
It should be the amount of millimeter of liquid column pressure lost per meter of pipeline.
I think it’s simply the amount of water column in mm lost after the fluid flows for one meter – that’s the unit of pressure loss!
