A fluid of density

enters a chamber where the fluid is heated so that the density decreases to
. The fluid then escapes through a vertical chimney that has a height L. Neglecting friction and treating the flow processes as incompressible except for the heating, determine the velocity, v, in the stack. The fluid velocity entering the heating chamber may be neglected and the chimney is immersed in fluid of density
