The flow rate in cubic feet/second is (3*1.5*3) = 14.5 cubic ft/sec.

According to Google, there are 6.229 Imperial gallons or 7.481 US gallons in 1 cubic foot.

Therefore, the flow rate is 90.32 Imp gallons/sec or 108.47 US gallons/sec.

If this many gallons flow per second, then (90.32 x 60) = 5419 Imp gallons flow per 1 minute, or equivalently 6508 US gallons per minute.

If rectangular about 21,000 gallons if oval about 16,000 gallons

If its an oval pool approx 7800 gallons at full capacity. If its rectangular pool then approx 9000 Gallons.

If rectangular: Lenght X Width X Average Depth X 7.5 = Volume in gallons.

Gallons in a rectangular tank =(tank's length in inches) times (tank's width in inches) times (water depth in inches) divided by (231)

-- Multiply (length x width x height) in inches; divide the answer by 231 to get gallons. OR -- Multiply (length x width x height) in feet; divide the answer by 7.481 to get gallons.

840,000 to 1,700,000 US gallons is flowing into the Gulf every day.

To calculate water flow rate, you need to know the cross-sectional area of the pipe or channel through which the water is flowing, as well as the velocity of the water. The formula for calculating water flow rate is Q = A * V, where Q is the flow rate, A is the cross-sectional area, and V is the velocity of the water. Multiplying the area by the velocity will give you the flow rate.
