Correct pipe rate units from galUS to galUS/h

CHANGELOG.md

@@ -72,6 +72,7 @@
 - Add support for slice notation in technology connections to allow users to connect between variables of different shapes. [PR 774](https://github.com/NatLabRockies/H2Integrate/pull/774)
 - Updated `commodity_sell_price` input to `ProFastNPV` to be per year of the plant life. Also updated `BasicProFASTParameterConfig.as_dict()` so explicitly input escalation values are not overwritten to the general inflation rate [PR 799](https://github.com/NatLabRockies/H2Integrate/pull/799)
 - Added `calc_azimuth_angle()` to `PYSAMSolarPlantPerformanceModel` to provide default azimuth angle based on whether the site is in the northern or southern hemisphere [PR 806](https://github.com/NatLabRockies/H2Integrate/pull/806)
+- Corrected water rate units in pipe feedstock from galUS to galUS/h [PR 813](https://github.com/NatLabRockies/H2Integrate/pull/813)
