So, we have a uniform velocity capital U that approaches plate or to U velocity, so we can non-dimensionalise the capital U, we have to be straightforward.
சோ, U velocity-க்கு, plate-அ approach பண்ற uniform velocity capital U-ன்னு இருக்கு, அதனால capital U-ஓட non-dimensionalise பண்ணிடலாம், straightforward-ஆ தான் பண்ணனும்.
