Calculating Thermal Resistance for Convection: Solving for Unknown Area

[williamx11373]

I need to use the equation below ( thermal resistance for convection)

R= 1/hAbut I am not given an Area, I am only given 4 meters as a thickness. how do I find A to use for the equation to solve for R.

How about assuming a width of 1 m? (And this assumption would need to be stated when referring to the resulting R value.)

well, if we make up our own are size... we'll get a resistance per unit area... so use like 1 m^2 for your area and R will be 1/4 ohm per meter^2

Then if we are actually given an area like 1/2 m^2 we could use the above equation or just times it by 1/4 to get 1/8 ohms.

not sure what else you could do with that given values.

edit: thickness = h ... right?
