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.
