AI Thread Summary
The discussion focuses on interpreting color transmittance reports that use the values L, x, and y. It is suggested that L represents the luminance component, which is commonly denoted as Y in color space terminology. Participants recommend researching "color space" and "xyY" for better understanding. There is some confusion regarding the absence of the "y" value in the report. Overall, the conversation emphasizes the need for clarity in color measurement terminology.

Dear folks

The case is this... to measure the color transmittance through a coating on a transparent sheet... and the values are in L, x, y [thought there should be a "y" but its not in the report]...

Can anybody shed some light on how to interpret L, x, y in this report ?

Thanks !

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
