when i use the pipe flow calculator, there are some values that i am not sure of, and i don't know how to get them or estimate them
or how important they are
they are dynamic viscosity, kinematic viscosity, pipe roughness (kr) and resistance coefficient (K)
the formula used is not displayed so i can't tell if an error in any of them is significant
also, how do you print out/save a calculated result?

Here you can find theory that is used for calculation:

Also, there is for dynamic viscosity:

friction factor:

and resistance coefficient K:

You can copy/paste results from report tab (selecting and using ctrl+c)
