In the given problem, it involves the design of a vertical Thermosyphon reboiler, taken from the bookCoulson and Richardsons Chemical Engineering Series, Chemical Engineering Design, Sixth Edition byRay Sinnott and Gavin Towler. Example $12\mathrm{.}11($page $474)$

If the height of the liquid at the bottom of the distillation column decreases by $75\%$ from its original value, analyze the impact on the circulation rate and further analyze how this will affect the distillation column. Specify the methods and steps for the calculation $($no need for numerical calculations$).$
