They can't collect and measure the spilled oil (if only they
could!), or get flow instrumentation down there. The only way to
estimate is to determine the cross section area of the pipe
opening, and the average velocity of the oil jet. They know the
diameter of the pipe, but the pipe was mangled first by the
accident, then by the shears. The pipe opening is not the ideal
shape for a calibrated flow nozzle, so a "spot" velocity from the
middle of the stream would not be very reliable, a velocity profile
would be required. Perhaps someone more qualified could make a
reasonable guess. Looking at the video, I haven't a clue how to
estimate.
IUt is not the "garbage out" of conversions, even multiple ones, it
is the "garbage in" of bad data.
Dear John,
I agree, in part, with your last line. Sure, there is garbage in, but
there is also garbage added in the dumbing down process, that might
add to the initial garbage.
You know the old euphemism GIGO for Garbage In Garbage Out. What I am
suggesting is GIGAGO for Garbage In Garbage Added Garbage Out. Sorry,
but I can't help you with the pronunciation of GIGAGO!

Dear Gene,
You might be interested in this article in our local newspaper, 'The
Age': http://www.theage.com.au/world/experts-at-loggerheads-over-oil-leak-rate-20100608-xtlj.html
Since each of the sources has their own 'down-dumber' I don't
suppose we can have any confidence whether the original data
(kilograms, litres, cubic metres, metres per minute, metres per
hour, gallons UK, gallons USA, feet per minute, etc, ) is being
reported reliable given the possibility of multiple conversion errors.
Cheers,

I *heard* on a news network that the Technical Team assigned to
measure the flow rate of crude oil and gas leaking from the floor
of the Gulf of Mexico is measuring depth in meters, *independent*
of BP statements.
What unit of flow rate is being used by the Team? I would like to
hear the rate in kg/s for each major hydrocarbon component of the
liquid and gas leakage.
Neither "barrels per day" nor "gallons per day" is acceptable.
