Problem 3.1 (use EES) Ammonia vapor is compressed inside a cylinder fitted with a piston. The following data have been experimentally measured during the process. Pressure [psia] Volume [in 3 ] 65 80 80 67.2 93 60.1 110 52.5 134 44.8 161 37.6 190 32.5 a) Determine the work done on the ammonia (in units of both ft-lbf and Joules) during this process by numerically integrating the data. Note that the EES Integral function can be used to do the integration. Choose the ammonia to be the system. W is the integral of P dV. We have P-V data and these can be numerically integrated. First, enter the data into a Lookup table. Select New Lookup Table from the Tables menu and specify 2 columns and 7 rows. Enter the data. The pressure at any given volume can be determined by interpolating the data. P=interpolate('PvsV',P,V,V=V) "pressure at specified volume" Now use the Integrate function to integrate the data from the initial to the final volume. We can also convert the units to ft-lbf in the same equation.

### 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.
