- 1 - Design of a Control Valve = Example 9.2 pg 219 and Figure 9.12 SEM2 This is an Example of using the MATLAB “cell” format in an m-file in order to “publish” the MATLAB program and results in a Microsoft WORD document – ready for additional editing. Note the use of %% to define new “cells” in the MATLAB editor. 2 40 30 (9-7) 200 v y q P P Δ = Δ = “A pump furnishes a constant head of 40 psi over the entire flow rate range of interest. The heat exchanger pressure drop is 30 psig at 200 gal/min ( q d ) and can be assumed to be proportional to q 2 . Select the rated C v of the valve and plot the installed characteristic for the following cases: (a) A linear valve that is half open a the design flow rate (b) An equal percentage valve ( R =50 in Eq. 9-3) that is sized to be completely open at 110% of the design flow rate.” See text = from problem specifications, calculate for (a) C v = 125 and for (b) C v = 115.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
