Calculation of Heat Transfer Rate and Enthalpies of Liquids
Question
A double- effect evaporator is to be designed to concentrate a 5.0% (mass) NaOH solution to 30%. Steam is available at 3300F, 77.3 psia and the condensing temperature of the vapor from the lowest pressure effect is 1800 F. an initial guess for the T of the first effect results in the values shown below:
Determine the information as required below. Fill in results on the diagram, but show work:
- Mass fraction NaOH in the liquid leaving the first effect and flows of process streams (L’s and V’s), assuming equal vapor rates from each boiler.
- Boiling temperature of solutions in each effect and boiling point elevation (note that the saturation temperature of water is given for condensing vapor streams).
- Enthalpies of liquids (gray boxes) and vapors.
- Heat transfer rate in each effect (Q1 and Q2)
- Amount of steam required
- Heat transfer area required for each effect if the overall heat transfer coefficient is 400 BTU/(ft2 hr 0F) in each effect.
Summary: This question belongs to heat transfer and discusses about a double- effect evaporator which is designed to concentrate a solution.

WHAT OUR STUDENTS SAY
When I was pursuing my course in Enterprise Resource Planning in supply chain management, I constantly took help from HwA and got instant result. The ERP expert here in HwA is very helpful and has helped me to complete the course with distinction.
Andrew Oliver Student
I am doing a long-distance executive marketing course from a Sydney based University and I really don’t find much time to devote for my marketing assignments. Thankfully, I have come across HwA, and they really know how to deal with these questions. The experts are well equipped and helped me get good grades in all my assignments so far.
Paula White Student
I was badly stuck with an argumentative essay writing assignment when I started searching for help on the net. I never thought that I will get any sort of specialized help for the Australian universities and when HwA promised to deliver that, I thought why not? Then I chatted with the expert and I got to know that she was also from the same university as I am in. It was kind of cool as she knew my syllabus and helped me out by writing and excellent essays which helped me get great grades.
Oliver Stuart Brown Student
Writing the final year dissertation paper was a big deal for me as it is the ultimate decider for my grades. Needless to say that I was very nervous but I got immense help from HwA throughout the tenure and helped me get a solid A at the end of everything.
Leslie Scanlon Student
I was very nervous when my thesis proposal submission date came closer. Only a week was remaining when my good friend Josh told me about TheReliableTutor.com. I was not sure but they did a marvelous job. Only within 4 days they prepared a wonderful Thesis Proposal and so I had assigned my entire Thesis to them and was very happy with the grade I got.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
