Solution to Pressure Difference Problem

[Jason03]

Hello,

Below is the problem and my solution. Everything seemed to work out correctly. Just looking for a second set of eyes to make sure.

Thanks

Seems right to me. Couple of minor comments:

Probably only accurate to 2 sig figs, unless you know the pipe area values are good to 4 figures?

Since it's a pressure difference between 2 sections of pipe, I'd use psi rather than psig units.
