hi ,my question is about convection!
Suppose that rod to the surface of a hollow cylinder connects . Temperature of the one side rod T1 and another side that attached to the cylinder isT2 . Temperature inside the cylindrical shell is T3., And T1 than T2and T3 from T2 is also greater.(T1>T2, T3>T2).and(T1>T3). find temperature at a point inside the cylindrical shell radius rx!long rod ,cylinder radius and conductivity and surface area of all the bars are clear.
I wait for your answer
