A funnel measuring 8 inches in diameter at the wide end, and 1 inch at the narrow end, is descending through 68 degree Fahrenheit fresh water, wide end pointing down, from a depth of 100 ft. to 200 feet at a speed of 1 foot per second.

When it passes the 200 feet mark, what is the velocity of the water exiting the narrow end, its pressure, and its flow rate? Please suggest / show the appropriate formula for the computation.

Here's how homework "works" on AMHD - and it's posted policy.

You post your formula and your answer.

Someone comes along and reviews it.

You learn absolutely nothing if we do your work.

You can always ask your professor for help or open your textbook.
