Temperature Control Of Poiseuille Flow With Particular Application To Flow Of Molten Glass.

The problem is that of controlling the temperature distribution of a fluid in fully developed laminar flow through a circular tube. It is assumed that suitable heating and cooling are available in a refractory casing surrounding the tube and that in its passage through a section of the tube and that in its passage though a section of the tube given length the mean temperature of the fluid has to be reduced (or increased) by a specified amount.
