no, it is the table who i want to plot the graph but i uploaded it on rapidshare. In the rapidshare is the excel file.

I have some data and i want to plot them on excel. I am trying to plot them but i am drilling a hole in the water. I will appreciate if anyone can help me with this. I want 3y axes and 1x.Thank you.

Yes i agree. But i want to prove how the emissivity formula is derived. Have a look here: http://en.wikipedia.org/wiki/Dimensional_analysis After this i hope that you will understand what i am looking to find.

Thanks for the reply tiny-tim. I know what is emissivity and i want to prove that emissivity is dimensionless. I know that is because is a ratio but i want to prove it through equations(dimensional analysis-using mass,length,time).

Homework Statement Does anyone know where can i find (book?) the dimensional analysis of emissivity? Homework Equations The Attempt at a Solution

Anyone? Too many members and no one knows what information is needed and how to calculate if a composite is possible? I have the specific gravity and elastic modulus of those materials. Do i need more information? Thank you

Hi, I am trying to understand some more on composite materials and i have a question. Let's say i have two materials and i want to produce a composite from those materials. How can i check if a composite is possible from these materials? I have found an equation on the web but i am newbie on...

yes it is a diy home made unit.

Hi, How to check my transmitter signal power? I have found my transmitter in my friend shed and needs some new output transistors. But i don't know what is the power of my transmitter and if it worth to repair it. There is the RF board and also a encoder. There is also an amp so i don't know...
