Question

A chemical engineer wants to design the reboiler in nucleate boiling regime and transition

region. Explain the advantages and disadvantages of both designs ( one in nucleate boiling and

transition boiling). Give your suggestion for this design idea.

Answer 1

Solution :

For designing of boiler in nucleate region , it have advantage of high heat transfer coefficient and heat flux while disadvantage is that it will have low temperature difference.

While designing the boiler in transition region the advantage is that it is a stable region and have highest temprature difference while disadvantage is that it will have lower heat flux and low heat transfer coefficient.
