3113Re: Rain Gauge Reading #2
- Jul 7, 2006Mason,
I found my old post on the approximate surface area of the rain
collector (I guessed 3" x 5", should be pretty close).
If WUHU registered a .81 increase in the rain total then you can
calculate the approximate volume of the water you poured.
If the rain collector is approximately 15 sq inches then:
.81 (in) x 15 (sq. inches) = 12.15 (cubic inches).
12.15 cubic inches is approximately 6.73 fluid oz.
Is it possible that you poured 6.73 oz versus 4 oz?
