You know how much is in the barge from how much you pumped, from the level indicator on the side, and from displacement.
Draft measurements will only give you a very approximate number. To more accurately measure the contents, you would walk out on the deck and drop a gauging tape down one of the gauging holes to measure the innage. From that you would use a prepared table for that particular barge that lists volume as a function of innage.
You'd be surprised. Styrene especially can be a problem, because it solidifies as it warms.Also barges tend to be empty when you start adding stuff to them.
All you need is video. Its not really that hard. A child could figure it out. They knew beforehand there was a possibility the think would clog up - they could have prepared to at least use that bad news to get a measurement. All you have to do is note the time the clog happens and have video on the thing. Sure, the point where oil starts to flow out the bottom won't be a precise moment in time, but it will be enough to got a rough estimate, and then you can go and model the flow inside after the fact to get a better estimate.For point 2, again 1 mile underwater. Also you would have only 1 shot at measuring if your method was really feasible. You would have to note when then spillover goes from clear to clouded, and would need laminar flow that miraculously bypasses the exitsting water in its way as it rises to the top of the bell.
That is a false excuse. ONE scientist at Purdue, with maybe a couple of grad students helping him, came out with this estimate, its not like it took a team of scientists. BP probably could have sent video of the leak to dozens of scientists and engineers all over the world who would have gladly come up with independent estimates free of charge to BP.And all this to measure something when instead they could be working to figure out how to stop it.
Estimating a flow from a plume shown on a video is basically guesswork. i dont care how good you think your model is. And again it is a big waste of time. The only people who seem to care about how much oil is leaking are those trying to make political statements out of it. The people trying to stop if have other things to worry about.
