1. ### Heat exchanger selection

may be it is too late for answer but i think this blog will help http://chemeng-processing.blogspot.com/2009/02/selecting-tema-type-heat-exchangers.html and this is a wonderful slid http://www.engr.iupui.edu/me/courses/shellandtube
2. ### How do I get water vapor fraction and pressure?

how can I get the vapor fraction by using steam table you can know the pressure on water and its corresponding temperature and amount of vapor generated. you can find steam table on most thermodydamic books.
3. ### Flow rate calculation using pressure difference and time

actually i already forget how i solved it but anyway downlod the following file and see the Example 2.1. i hope it will help http://faculty.kfupm.edu.sa/CHE/zaidismj/Teaching/CHE204_072/Module2_lec4.doc
4. ### Non linear curve fitting

give us the points and I may able to interpolate it with different method.
5. ### Heat constant change with temperature

why not R=Cv-Cp (not sure but something like that) i think there are another way to find Cv. try to have a look to this book. http://www.3mints.info/upload/uploads/e1b85696fd.jpg unfortunately I'm away from my home , so i can not give you the equation directly.
6. ### Heat constant change with temperature

just h have to be interpolated , but you might find empirical equation describe behavior of h with respect of T if you search through internet (difficult and time consuming). Pr,Nu,Re , vescosity and Cp have a specific equation.
7. ### Heat constant change with temperature

I do not actually understand your question, but to find Cp at different temperature there are an equation with many constants you can find it at the end of this book or i thing you will find that equation in Perry Chemical Engineering handbook...
8. ### Flow rate calculation using pressure difference and time

- Rate of mass = Rate of accumulation of mass - Q\rho = d/dt (V\rho) ** Q is volumetric flow rate & V is vessil vloume = V d\rho/dt + \rho dV/dt ** \rho is density = V [d\rho]/[dt] ** since Volume of vessel is...
9. ### Flow rate calculation using pressure difference and time

What do you mean by ''inside diameter of part: 3/8" ' diameter of pipe or orifice or what??
