ya defiantly ocm lectures lot's of information but plz make some starting portion or ppt of which topics we have Learn so it more usefull...and thankxx..
What is heat radiation and is it like electromagnetic radiation? Heat can transfer in vacuum also but how? When anything is heated then its molecules vibrate rapidly but why anything that comes near that object also heats up? Is it something like electromagnetic radiation?
@ 42:18 he writes: "If all surfaces are plane/convex -->self view factor is zero. But then he actually draws a convex surface and says that the self view factor =/ 0? Did he mean concave?
He mean concave and draw the concave surface. Actually same surface can be consider concave or convex depending on, from which side you are seeing. here he meant concave if the radiation is emitted in upward direction.
This professor is a superb lecturer. I now have a much better grasp of radiation heat transfer. If only my professor was this good.
How can some dislike this amazing lesson? 😡
i love the way he's teaching! thanks a lot sir, help me a lot though :)
Could you please make the introduction music louder I still have some HEARING LEFT!!
Great proff makes students to think all things we know
Very nice lactere about the calculation of view factor....!!!!
Great teacher.
is there amything about radiatoin shield?

Thanks Sir . Could i be a student of you?
