Can Mass Flow Rate Determine Pipe Length?

[emilynb]

I have a mass flow rate, an area for the pipe and thus the diameter. I need to know the length of the pipe, but I end up with one equation and 2 unknowns. Is it possible to use the mass flow rate to somehow find the volume, which, in turn I can use to calculate the length? Or, any other suggestions are welcomed.

Thank you!

Is this a homework question or a real-world question? In either case, you don't have enough information to answer it. Pipe length is rarely something to be calculated.
