### 1/5 — Needs work

*2020-01-17, version 2.0.0*

The values that can be inputted are extremely limited. The orifice calc won’t work on static’s above 2” - and there is no evidence or reference information to confirm the validity of the calcs.  Couldn’t get the friction loss calculator to work at all.  The purchased version is not worth the price with these issues.  Thx
