A refrigerant is compressed in the compression cylinder of a refrigerator from p1 = 112 psi, V1 = 13.0 in3 to p2 = 424 psi, V2 = 3.0 in3.
a) Determine a value of n such that the data are fit by an equation of the form pV n = constant. Hint: You can take the logarithm of this equation such that the form becomes similar to y = nx + b, and you can solve for n by simultaneous solution of the equation at state’s 1 and 2.
b) Evaluate analytically the work done on the refrigerant, in BTU, using the equation for compression expansion work along with the result of part (a)
