Coefficients for standpipe:
Department standard: 25 + lines
Intake drop:

Process to add lines:
1) Take Static reading on intake after hitting source.
2) Get residual reading.
3) Take Static reading, and - residual reading.
4)Times difference by 100.
5)Take that difference and divide by the static reading.
