Hi Richard,
Sorry for the typo and unit mix-up, agreed should be 63 cf / 15m. I also found a mistake in my spreadsheet and now agree the nozzle in / hr appears to be 18.552. I’m m aking a meal of this.
Also agree this seems ridiculously high. I must be reading the meter wrong, and infact just noticed that the dial numbers are tenths (didn’t see the tiny decimal points). Here’s a picture of my water meter, It’s a Badger Water Model 25: https://www.dropbox.com/s/2qpyc411z1sm6hi/2021-05-12%2011.37.07.jpg?dl=0
So, here’s how it read before and after, the square brackets show the black numbers, and the angled bracket shows where the pointer was on the dial:
Start: 0158 [46] <.92>
Finish: 0158 [53] <.20>
So I think my original placing of the decimal was correct, and the flow rate is actually 25.2 cuft/hr
This would come out to Nozzle inches per hour of 1.855, which seems more reasonable. Right?
