how much 1" rock will I need to fill in a hole 20' long, 2' wide' and about 2' deep
Simple 3x14=42cubic inches so at a rate of 9cubic inches per minute. 42ci/9ci/m=4.7m then you multiply 4.7 by 60 to convert to seconds as it is the standard form for most physics. 4.7x60=282s so it would take 282 seconds to fill the cylinder
With a 6 inch diameter and with 1 mile = 5280 ft = 63360 inches.Volume = (cross sectional area) x ( length) = pi * r2 * length = pi*(3 in)2 * 63360 in = 1791461.79 cubic inches.1 gallon = 231 cubic inches, so it is 7755.25 gallons

The question cannot be answered. You could have an infinitely long but infinitesimally thin cylinder, or an infiniteimally short but infinitely wide cylinder. In between these two extremes there are an infinite number of possible combinations.
depends on water pressure, but it should completely fill in 15-20 minutes. the water should be hot in another 20-25 minutes if it has been run completely empty.
The time it takes to fill up a 50-gallon water heater depends on the water supply flow rate, typically measured in gallons per minute (GPM). If the flow rate is around 5 GPM, it would take approximately 10 minutes to fill the tank completely. However, this can vary based on plumbing, water pressure, and the specific flow rate of the faucet or valve being used.
Usually about an hour.
The time it takes for a hot water heater to fill up completely can vary depending on the size of the tank and the water pressure. On average, it can take anywhere from 30 minutes to an hour for a hot water heater to fill up completely.
it only depends on pressure at which the water flows into the gallon
Around 3 hours
Around 3 days depending on water pressure.
Ususally about an hour or so...
I gallon of Long Life Coolant mixed with 1 gallon of distilled water will be enough to fill it up after draining.
Most are rated for 5-10 years depending on cost.
The answer depends on the flow rate or the water pressure, not just the pipe size.
About 4 seconds as it comes crashing to the ground
