Water Delivery

[Durian Fiend]

NWS says for OLE today:  Isolated showers after noon. Mostly sunny, with a high near 81. South wind 5 to 10 mph becoming light west. Chance of precipitation is 20%.

Just in case, I cleaned all my downspout screens.

I also asked Bard's AI how much water I have.  Is it right? I don't know:

A perfectly round tank 18 feet across and 64 inches high with a flat bottom has 20 inches of water in it.  How many gallons of water is in the tank and how many gallons would be in there if the tank was full?

For the water-filled portion:

Radius = 18 ft / 2 = 9 ft
Area of base = pi * (9 ft)^2 = 254.47 ft^2 (not inches!)
Height of water = 20 in / 12 in/ft = 5/3 ft
Volume of water = area * height = 254.47 ft^2 * 5/3 ft = 424.12 ft^3
Gallons of water = volume / cubic inches per gallon = 424.12 ft^3 * 7.48 gal/ft^3 = 3163.2 gal (rounded to two decimal places)

For the full tank:

Height of full tank = 64 in / 12 in/ft = 16/3 ft
Volume of full tank = area * height = 254.47 ft^2 * 16/3 ft = 1346.08 ft^3
Gallons of full tank = volume / cubic inches per gallon = 1346.08 ft^3 * 7.48 gal/ft^3 = 10040.2 gal (rounded to two decimal places)

Therefore, there are 3163.2 gallons of water in the tank right now and there would be 10040.2 gallons if the tank were full.

It's correct.  An easier way to do it would be to multiply the fractional amount of water left in the tank by 10,000.  20/64 X 10,000 equals 3,125.

Bob Farrell on FB weather adds this interesting info regarding recent conditions.  

"In a rather unusual synoptic weather pattern across the Pacific, the Subtropical Surface Ridge has remained over and even just south of the Hawaiian Islands. This Subtropical Ridge is normally situated and makes up what is known as the Horse Latitude belt. at a Latitude much farther north, as per this definition from the American Heritage Dictionary: 'either of two belts of latitudes located over the oceans at about 30° to 35° north and south, having high barometric pressure, calms, and light, changeable winds.' This is a rather precise description for Hawaiian Island weather for most of January, as this ridge has resided much farther south, close to 20N, which has pushed the normal trade wind belt well south of the islands through most of January. This has left the Hawaiian Islands in the northern belt of the Horse Latitudes, where it remains today."

More weather trivia from the National Weather Service:

"Stable conditions are expected to develop late next week as high
pressure builds in behind the front. This will result in the long
awaited return of breezy trade wind weather. An interesting side
note, the last time we saw trade wind conditions was January 1st.
Given the current forecast we will end the month of January with
only one trade wind day (we typically see trade winds around 50%
of the time in the month of January)."
