The rate of heat transfer through a pipe wall is given by, q = 2π k (Ti – T0)/ln (ri/r0). For cylinder of very thin wall, q can be approximated by__________________?
(A) q = [2π k (Ti + T0)/2]/ln (ri/r0)
(B) q = 2π ri k (Ti – T0)/(r0/ri)
(C) q = 2π k (Ti – T0)/(r0/ri)
(D) q = 2π k (Ti – T0)/[(r0 + ri)/2]
