A mixture of containing 60 mol% ethylene (C2H4) and 40 mol% acetylene (C2H2) at 6 MPa and 300 K is passed through a preheater and exits at 6 MPa and 400 K. A) Calculate the inlet specific volume using: The ideal gas EOS i) ii) The Kay's rule i) where, a = 27R2(Tc)?/64PC and B = RTc/8Pc The van der Waals EOS [P = (RT/(v-b)) - (a/v²)] Comment on your answers to A (i), (i) and (iii) above B) Use the Kay's rule and calculate the specific heat transfer in the iv) process Data: Properties. C2H4: CP(ave) = 48.06 J/mol K; Tc = 282.5K; Pc = 50.6 bars C2H2: CP(ave) = 7.28 J/mol K; Tc = 308.2K; Pc = 61.9 bars A mixture of containing 60 mol% ethylene (C2H4) and 40 mol% acetylene (C2H2) at 6 MPa and 300 K is passed through a preheater and exits at 6 MPa and 400 K.
