Q11) For radial system (cylinder) with one dimension, steady state, no heat
generation. Determine the heat flow through the cylinder. Note that the inner radius of
cylinder (ri) and the outer radius is ( ro) with length (L).
Q12) Derive an expression for the overall heat transfer coefficient (U) for one layer
plane with
convection heat transfer from both sides?
Q13) consider a medium in which the conduction equation is given in its simplest form
as:
a- Is heat transfer steady or unsteady?
b- Is heat transfer one, two or three dimension?
c- Is three heat generation in the medium?
d- Is the thermal conductivity of the medium constant or variable?
