2.24 Measured data for pressure versus volume during the compression of a refrigerant within the cylinder of a refrigeration compressor are given in the table below. Using data from the table, complete the following: (a) (5 pts) Determine a value of n such that the data are fit by an equation of the form pV" = constant. (b) [5] Plot the data and the curve fit from part a as a plot of pressure versus volume. () [4] Evaluate analytically the work done on the refrigerant, in Btu, using W = (pdV (Eq. 2.17) along with = par the result of part (a). (d) [4] Using graphical or numerical integration of the data, evaluate the work done on the refrigerant, in Btu. (e) [2] Compare the different methods for estimating the work used in parts (b) and (c). Why are they estimates? V (bf (in) in? 142 17.0 172 15.0 213 13.0 11.0 274 370 9.0 540 7.0
