Question:-
In a long cylindrical rod of radius R and a surface heat flux of q0, the uniform internal heat generation rate is
Option (A)
2 q0 /R
Option (B)
2 q0
Option(C)
q0 /R
Option(D)
2q0 /R2
Correct Option:
(A)
Question Solution:

Tw = (`qR/2h) + Tf
Tw - Tf = (`q.R/2h)
Surface heat flux q0 = h.(Tw - Tf)
q0 = h.( `q.R/2h)
`q = 2q0/R
