Some even say it was there all along. I for got - for pressure they need a tap into the casing as far as i know there is no way to measure it externally.

Could be and for the exact pressure You are right, I believe.
How does the pressure give them the velocity?
Sorry, I am a math dunce.
cause pressure drop is the driving force for determining the flow rate.
W = K * (dp)^.5
Using this formula, the flow rate is determined by a constant (K) and the square root of the pressure drop.
A more general formula is:
W = 1891 * d^2 * (dp * rho / K ) ^.5
where K is f * L / D
In this formula,
the little d is the diameter of the pipe in inches.
rho is the density of the fluid
K is the resistance of the piping. It is calculated from the friction factor (f); the length of the pipe in feet (L) and the diameter of the pipe in feed (D).
since all of these terms (except the pressure drop) are constants, once they are calculated, they can be used to reduce the equation to the first, more simple term.
>>> Why was this NOT done the first few days? Common sense says to know the size of the leak up front!! <<<
No, common sense says the leak was huge, put all your efforts into stopping the leak. There is plenty of time later to estimate how big it was.
>>> There is no good way to measure the flow rate unless they can figure out a way to run it through a pipe. <<<
and fortunately the flow just so happens to be running through a pipe. A nice long pipe that runs through the ground.
So all they have to do is to get the sensors down into the existing pipe, before the leak, and voila, they have the answer between how much is getting into the boat and how much is going into the ocean.

Exactly and the same with bashing BP now is the time to help not drive them out of business. there is a time and place for that after the leaking is under control.
I read an article yesterday quoting a BP official as saying the extra containment apparatus they hope to have installed next month will bring the total oil captured up to 2 MILLION GALLONS DAILY. Yes, you read that correctly.
SO,
that tells me that it is spewing AT LEAST 2 MILLION GALLONS DAILY.
I’m sure BP and our govt. have known the flow since April 21.
2 million gallons is a shade under 50,000 barrels. That’s a major well—I wonder about the size of the reservoir they hit.
