Engineering Number News Today

Say plus/minus 1%. really hard, good engineering number. and because of the -- because of the various variables here, im not able to get, im not confident beyond plus or minus 20%. >> so the estimate of 5,000 gallons. you have -- a day -- you have no doubt that is way, way low. >> right. >> you are saying it could be as high as 70,000? >> well, i calculate from the video, which is just a snapshot in time, right, the video just shows what was happening i think it was shot the day before yesterday...

Explain, answer the first question. the second question, i guess i would have to leave to others. so to briefly walk you through where this calculation comes from, its -- based on a measurement technique of fluid measurement technique, particle image velocity symmetry. scientific word for measuring flows using, look at how fast particles move. >> you basically look at this for two hours, i understood. measured the speed at which and rapidity at which particles were moving through this video. bec...

Margin of error? >> thats right. when this technique is done correctly, in a laboratory setting, the window of error is very small. say, plus, minus 1%. really hard, good engineering number. and because of the -- because of the various variables here, im not able to get, im not confident beyond plus or minus 20%. >> so the estimate of 5,000 gallons. a day you, have no doubt that is way, way low. >> right. >> you are saying it could be as high as 70,000? >> well, i calculate from the video, which...
